The problem aims to answer three questions: a. Initial kinetic energy needed to reach a turning point 10 10 10 fm from the nucleus. b. Kinetic energy the proton of a has when it is 20 20 20 fm from the nucleus and moving toward it. c. Kinetic energy the proton of a has when it is 20 20 20 fm from the nucleus and moving away from it.

How much kinetic energy to kill a deer. ... kinetic energy, just part of why he felt he had enough power. ... How much the deer moves, deflection of the ... how far a lot of guys shoot. No ...

For instance, Hornady's popular 250-grain 20-gauge SST sabot slug produces 1,200 foot/pounds of energy at 100 yards, 983 foot-pounds (ft.-lbs.) at 150 yards, but then tails off to 815 ft-lbs at 200. Many state DNRs recommend 1,000 ft.-lbs. of energy at the target to anchor a deer, but there's no data that has shown that to be the benchmark.

The kinetic energy formula works in classical physics, but it starts to deviate from true energy when the velocity approaches the speed of light (c). How to Calculate Kinetic Energy. The key to solving kinetic energy problems is to remember that 1 joule equals 1 kg⋅m 2 ⋅s −2. Speed is the magnitude of velocity, so you can use it in the ...Kinetic energy powers the bullet expansion and penetration that destroys tissue, and it is the destruction of tissue (vital organs if the shot is a good one) that kills the animal. All of the common revolver hunting cartridges (.357 Mag., .41 Mag., and .44 Mag.) are medium bore or big bore calibers. It is no secret that such calibers, primarily ...B. During the collision, how much kinetic energy is converted. A 1000-kg car traveling east at 50 km/h passes over the top of a hill and hits a 2900-kg truck stalled in the middle of the lane. The impact causes the truck to roll eastward at 15 km/h. A. During the collision, how much kinetic energy is converted to internal energy in the Earth ...Many a deer has been killed with .224, .243 and .257 caliber cartridges, so there is no reason that a .264 isn't up to the task. It's also big enough to double for larger game like elk. If we stay in the lower velocity ranges of the 6.5-284, 6.5×55, 260 Remington and the 6.5 Creedmoor, mild recoil is a big plus.What you will gain with a 70# bow over a 60# bow is about 20-25 fps depending on the bow. You will also gain 10-13 lbs. of Kinetic Energy. Example of a bow i set up. 29/70 375 gr. arrow at 327 fps = 89 lbs. of KE. 29/60 375 gr. arrow at 302 fps = 75.9 lbs. of KE.How much kinetic energy does the car have before it hits the brakes? b. Where does this energy go when the driver brakes to a stop? c. What is the work done by the car's brakes? ... The energy is entirely dissipated by the force of friction in the brake system. (c) W = delta KE = KEf - KEi = (0 - 240,000) J = -240,000 J (d)New Hampshire. "Experts" will tell you anywheres from 1000-1200 ft/lbs. This, to me, is waaaaay overkill. One gentlemen, whos advice I trust completely, has a good formula. 3 times as many ft/lbs is needed than the games weight. Meaning if you want to shoot 200 lb deer then 600 ft/lbs should do the job very nicely.

The greater the amount of kinetic energy transferred, the larger the temporary cavity. The size of the temporary cavity varies depending upon the interplay of bullet velocity, mass and design (Fig. 3). When fired into a cranium, the vault represents an enclosed container that cannot expand to absorb the kinetic energy, but fractures.Science. Physics. Physics questions and answers. One car has twice the mass of a second car, but only half as much kinetic energy. When both cars increase their speed by 8 m/s they then have the same kinetic energy.What is the original speed of the lighter of the two cars?Pushing a bullet weighing around 700 grains (or more) at velocities approaching 3,000 fps, there's no denying that the .50 BMG really packs a punch. However, many people have also claimed that the cartridge is so powerful that the shockwave from a .50 BMG is strong enough to kill or seriously injure a person, even if the bullet itself misses.Let's say you're shooting a heavier arrow that weighs 500 gr. That means it has about 64 ft-lbs of kinetic energy when it leaves the bow. During the flight, some of that energy will be lost to wind resistance. When the arrow makes the impact with the deer, all of the remaining energy is transferred to the razor sharp edges of the broadhead.Colorado. Oct 1, 2014. #9. I agree with what has been said, and also use a ballpark of 1500 ft*lbs as a minimum energy for elk. Although, I have never had the opportunity to test 1500 ft*lbs. My furthest shot on an elk still carried over 1850 ft*lbs at 630 yards with a …We also know the value of k which is 450395. Applying these values to the formula: Muzzle Energy = 140 * (1200 ft/s)^2/ 450395. Solving for the squared velocity: Muzzle Energy = 140 * 1440000 / 450395. Calculating the muzzle energy: Muzzle Energy = 447.60 ft-lbs. Here, the intrinsic relationship between the bullet's mass and its velocity ...Feb 8, 2019 ... You have surely heard and may possibly believe that the killing power of a cartridge is represented by kinetic bullet energy.

But it all hinged on the kinetic energy transfer theory, which turns out to be incorrect. Where it All Goes Wrong. From at least the late 1800s through the Vietnam War, everyone assumed the kinetic energy transfer model was correct. The "shock" of getting hit by a fast-moving projectile and absorbing its kinetic energy contributed to ...Location. MN. Mar 23, 2024. #33. Hit that North Dakota Buck with a nearly 2,288,000 grain slug ( 1997 GMC K-2500 Suburban ), that was traveling around 110FPS (75mph). A guy would think 61,468 ft lbs of energy would a stopped him, nope, not even a decent blood trail.It launches a 320-grain carbon arrow/broadhead at 198 fps and produces about 28 pounds of kinetic energy. That's pretty light, but it's obviously enough to bring down a big hog and a whitetail. Shot placement with a good broadhead is the key.In general, an arrow loses five feet of its kinetic energy per 10 yards after impact. So for a 40 lb bow firing out a 300 grain arrow at 230 fps for 50 yards shot from this same bow will only have 28 feet-lbs left upon impact at impact. As such, less kinetic energy is required than many hunters believe to kill a deer.

In conclusion, I don't think a person could reliably hunt dear with a thrown rock, or even a slung one beyond an anecdotal fluke. A lower limit on a speed you would need to seriously exceed 200m/s (~450mph) if you wanted to try. Of course there must exist some minimum peed it can be propelled that would kill a deer. supersonic baseball cannon.Excalibur doesn't make a hunting crossbow that isn't more than equipped to deliver sufficient KE to kill a deer. Considering that most if not all jurisdictions have a minimum (and even maximum sometimes) draw weight for differing species of animals, your question has already been answered by the imposition of a minimum draw weight. 40# at 28 ...The faster bleeding caused a much faster kill and this in turn enabled the hunter to locate downed game from within a short distance of the initial shot rather than the common risk of being unable to locate the dead animal. ... The projectile transfers its kinetic energy to the surrounding tissue causing acceleration of fluid particles in and ...Kinetic energy is energy in motion. A 150-grain bullet standing still has potential energy. Dropped, it has a bit of kinetic energy, and you’ll feel this should it land on your naked toe. Push this same bullet with about 50 grains of Hodgdon 4350 powder behind it, and you won’t want to feel it on your toe or anyplace else. It will be ...

The efficient killing of deer-size game, taken-as-they-come, is supposed to be dependent on a striking energy of at least 1000 ft/lbs, with wapiti requiring at least 1500 ft/lbs. ... The most reliable observers of killing power have concluded that kinetic energy is what determines a bullet’s total destructive ability – in volume of tissue ...The initial K.E. generated at the shot is 71.53 ft./lbs. (To determine how much initial kinetic energy your own bow-and-arrow set-up has at the shot, the formula is which is arrow weight (mass) x velocity squared, divided by 450,240.) Most experienced bear hunters I know believe that for averaged-sized bears taken at reasonable ranges—under ...In the hunting fields, especially in the deer woods, the .300 BLK is an acceptable, if not overwhelming choice. If ranges are kept around 100 yards—much like the .30/30 WCF—things should go right for you. Were I using a Blackout on a deer hunt, I'd most definitely choose a premium hunting bullet in the 125- to 135-grain range, as they ...Smaller calibers require great skill. When you increase the caliber size from .177 to .22, .25, .30, .357, .45 and upward, then the precision required for a humane kill decreases. There are some calibers that are very well suited for various types of game. The general rule in the airgun world has always been .177 for feathers and .22 for fur.MO/KS state line. I think MO did away with their old minimum of 30# DW but if you calculate with one of the online calcs...a bow with a 325 IBO and a 324 grain arrow with a draw weight of 35# is only about 41 ft lbs of KE which is widely considered adequate to kill a whitetail deer.For deer hunting, it is recommended to have a ballistic energy of at least 1,000 foot-pounds to ensure a clean and ethical kill. 1. What is ballistic energy? Ballistic energy is the measure of a bullet’s ability to penetrate its target. 2.It's only from 300 FPS and up that you get enough kinetic energy at all feasible hunting distances (up to 50 yards) to be able to comfortably hunt elk. As such we recommend that elk hunters stick to 300 FPS or more. For whitetail deer this requirement is lower - any crossbow 250 FPS and up will be a safe pick.But energy is a rough estimate of killing power only so long as you are comparing two reasonably similar calibers and bullets in terms of sectional density. Compare a 200-grain bullet fired from a .35 Remington rifle to the same bullet fired from a .350 Remington Magnum and you’ll find that the magnum’s bullet carries more energy to the ...The 7mm Rem Man and 300 Win Mag cartridge cases are similar in size, but the 300 case has a capacity advantage of about 6 percent. So, with the same weight bullet, the 300 will have a slight ...Depending on the bow you use and the arrows you use, your kinetic energy could range from 30 foot pounds at 30 yards to almost 125 foot pounds at 30 yards. These numbers are dependent on the FPS of the crossbow. The higher the FPS, the higher the kinetic energy will be. As the arrow moves through space, the kinetic energy drops.

It's only from 300 FPS and up that you get enough kinetic energy at all feasible hunting distances (up to 50 yards) to be able to comfortably hunt elk. As such we recommend that elk hunters stick to 300 FPS or more. For whitetail deer this requirement is lower - any crossbow 250 FPS and up will be a safe pick.

Michelle's Hoyt Trykon Sport, the one she used to kill the hog, is set at 40 pounds and has a draw length of just 23 inches. It launches a 320-grain carbon arrow/broadhead at 198 fps and produces about 28 pounds of kinetic energy. That's pretty light, but it's obviously enough to bring down a big hog and a whitetail. The killing power of an arrow is measured in Kinetic Energy. Think of it as the force behind the arrow that drives it. More force equals deeper penetration. ... the minimum KE required for deer-sized game is 25 pounds. Most modern bows with at least a 30- to 40-pound draw weight and a 24-inch arrow can achieve that. ... A stand over 15 or so ...Michelle's Hoyt Trykon Sport, the one she used to kill the hog, is set at 40 pounds and has a draw length of just 23 inches. It launches a 320-grain carbon arrow/broadhead at 198 fps and produces about 28 pounds of kinetic energy. That's pretty light, but it's obviously enough to bring down a big hog and a whitetail.Since the announcement of the SDI program in the mid-1980s the United States has spent about $100 billion on missile defense with a primary focus on the kinetic energy or hit-to-kill concept. U.S. programs began looking at that concept a decade earlier into the mid-1970s. Supporters of hit-to-kill could argue that what the United States is ...An arrow or bolt’s kinetic energy is greatest immediately after being discharged from a crossbow’s string. This energy also dissipates rather quickly with each yard of arrow flight, meaning that a bolt or arrow strikes a target with much more kinetic energy at 20 yards than it does at 50 yards.Posts. 1,123. There is no regulation on FPS, only on page 24 of the regulations... " crossbows must have a draw length of at least 300 mm (11.8 in.) and a draw weight of at least 45 kilograms (99.2 lb.). At a minimum bolts must have a 22 mm (0.87 in) wide head with at least two sharp cutting edges." Find a bow that fits you, shoulder the bow ...10664 posts · Joined 2004. #6 · May 31, 2006. The typical posted minimum is 55 ft pounds, but I have personally killed quite a few with less before I knew any better. The deer didn't seem to notice. You need to find out your arrow speed and then calculate K.E. The formula is: speed x speed x arrow weight / 450240.A recent example that demonstrates this clearly is this video by DIY Sportsman. The data given spans arrow masses from 379.4 grains to 1163.5 grains. That is an increase in arrow mass of 207%—a tripling of arrow mass. The kinetic energy of the arrow leaving the bow increased from 73.3-77.9 ft·lb., a mere 6% increase.During an ice show a 45.0 kg skater leaps into the air and is caught by an initially stationary 55.0 kg skater. (a) What is their final velocity in meters per second assuming negligible friction and that the 45.0 kg skater's original horizontal velocity was 4.00 m/s? (Enter a number.) m/s (b) How much kinetic energy is lost in joules?

How many feet per second does it take to kill a squirrel?A .30-06 pushing the same bullet would produce closer to 3,000 ft-lbs. Even the little .243 Winchester throwing a 100-grain bullet 3,100 fps cranks out more muzzle energy—2,100 ft-lbs—than the .30-30. And it retains more of it downrange. At 200 yards, the 30-30 bullet's energy has dropped to about 1,000 ft-lbs.Kinetic energy is the movement energy of an object. Kinetic energy can be transferred between objects and transformed into other kinds of energy. [10] Kinetic energy may be best understood by examples that demonstrate how it is transformed to and from other forms of energy.Speed alone is not a good indicator of a bows ability to harvest an animal. The question you should be asking is "how much kinetic energy do I need to humanely harvest a deer?" The general answer to that is something around 45 ft/lbs. Kinetic energy is a factor of the speed and weight of the arrow. The amount of KE produced is easily …how many people would think of shooting a deer or moose at 600 yards. ... When I was much younger I made a super kill ... Kinetic energy by its very ...A generality is that around 1200 ft. lbs. of energy on target is necessary for humane elk kills. Another is that the rifle caliber should be .270 or greater. I think that bullet placement is much more important than kinetic energy or bullet diameter, but this can serve as a rough guide to caliber and the maximum range at which a given load ...I'm going to give the muzzelloading season a try again after about 10 years not doing it. Still going to use .44 cal Hornady 240gr hollowpoints with 50cal sabots from a TC System 1. Also, two 50gr pellets. It worked the last time I shot a deer, so it probably will work again, Good Luck Dave. Oct 6, 2009.MO/KS state line. I think MO did away with their old minimum of 30# DW but if you calculate with one of the online calcs...a bow with a 325 IBO and a 324 grain arrow with a draw weight of 35# is only about 41 ft lbs of KE which is widely considered adequate to kill a whitetail deer.Velocity is the main contributing factor to kinetic energy, which packs the punch that makes quick ethical kills. In a given calibre, the lighter bullet is faster and so it can produce more kinetic energy. ... many experts say to kill a deer ethically takes terminal energy of 1,000 foot pounds (ft-lb), some say 800 ft-lb, and others commonly ...I've always suggested using Energy (lbs) thats (4 x the animals weight). Example a 200 pound deer needs 800ft.lbs. energy. deer: 700-1400lbs. "Energy". Elk: 1400-2000lbs. of course there is lots of varibles but this is a good rule of thumb.Kinetic energy figures can be misleading, however, if dissimilar calibers and bullets are compared. The same Remington ballistics table that provided the energy figures for the .270 and .30-06 loads above also shows that the .30-30 factory load using a 150 grain Core-Lokt bullet carries 1296 ft. lbs. of kinetic energy at 100 yards. ….

How Much Energy You Need for a Clean Kill. ... Without turning this article into a physics lesson, every moving object has kinetic energy. You will see this in ballistics data, and the elementary calculation is one half time the mass of the bullet times its velocity squared. ... Minimum Bullet Energy (ft-lbs) Whitetail Deer: 1,000: Pronghorn ...This weight is more appropriate for whitetail deer and other small-medium sized game. The 243 Win's muzzle velocity hinges on its bullet weight. At 55 grains, its bullet achieves 3,910 fps; at 100 grains, 2,960 fps. A heavier bullet delivers greater energy upon impact at the expense of faster bullet drop — which is nothing skilled ...All have you to do is square the velocity, multiply by the arrow mass, and divide it all by 450,240. Easy! Here's an example. Let say your bow setup shoots a 400 grain arrow at a respectable 250 fps, the computation of your kinetic energy or "knock down power" will be: KE = (mv ²)/450,240. KE = [ (400) (250²)]/450,240.In hunting, how much damage a bullet does is more important than its toughness. A bullet that sheds weight and deforms chaotically causes more damage. Conventional mono-metal bullets dump about 50% of their energy in the first 8 inches. Traditional cup-and-core and lead core dump about 80%. Somewhere along the way, the …A 2 kg stone moves with a speed of 1 m/s. A second 2 kg stone is moving twice as fast. Compare their kinetic energies. A.

F.The kinetic energy of the projectile drops dramatically the further downrange it travels primarily due to energy lost in the form of heat generated by friction against the air itself. ... but in most states, it's illegal to use a .22LR for deer hunting. This is because the .22LR has too low of impact energy to kill a deer humanely and quickly ...A stronger draw weight will generate faster arrow speeds, more energy, and deeper penetration, so dial up your weapon as much as possible. You'll want 50 pounds of draw weight as a bare minimum. Choosing the Right Arrows for Hogs. If your target is a big trophy boar, you probably won't be able to tag one with your deer hunting arrows.Just wondering how much kinetic energy everyone is getting out of the hunting setups. '09 PSE Bowmadness Sword Twilight Hunter Trophy Taker FC Rest Trophy Ridge Crush 350 arrows, ... And KE doesn't kill deer, but it sure helps, especially if there is something in the way. - Guns for show :uzi:, bows for a pro :archer: - - Become one with Nature How much kinetic energy to kill a deer, Kinetic Energy is the energy an object has owing to its motion. In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 ..., A local team has drafted an up-and-coming, left-handed pitcher who can consistently pitch at 41.12 m/s (92.00 mph). Assuming a pitched ball has a mass of 0.1426 kg and has this speed just before a batter makes contact with it, how much kinetic energy does the ball have? Kball ہے Recall that the acceleration due to gravity is 9.81m/s2., Imagine that much kinetic energy concentrated into an object the size of a bullet, or a pellet, or a super cool .50 caliber arrow. Now imagine 350 foot pounds in a bullet, or a pellet, or a super cool .50 caliber arrow, and then remember that many PCP’s intended to hunt deer and other types of bigger game will exceed that number., Then .051/32 = .0016 slug. finally. .0016 x 280 = 0.448 s/fps momentum. Now, given broadheads of identical design, cutting width and sharpness, the combination with .500 slug-feet per second momentum will penetrate better than the faster but lighter combination at .448 slug-feet per second. If we had used the formula for kinetic energy, the ..., Kinetic energy equals velocity squared, multiplied by mass, divided by 450,240. The sum equals the kinetic energy — a.k.a. KE in foot pounds — of an object in motion. ... Just as you can cleanly kill deer with a .22 Hornet, you can also kill elk with wide-cutting mechanicals and light arrows — if everything proceeds according to script ..., When it comes to bows, energy is stored in the limbs and cams when the bow is drawn, then transferred to the arrow shaft at the shot in the form of kinetic energy, or K.E. My 28½-inch Easton 4mm FMJ shaft tipped with a 100-grain broadhead weighs in at 380 grains – a medium-weight shaft that will produce enough K.E. and momentum when shot ..., In order to kill a deer with a crossbow you need to deliver a minimum of 1000 foot-pounds of kinetic energy into the animal. This can be accomplished with a well-tuned crossbow shooting arrows that weigh at least 400 grains at a minimum of 250 feet per second., Location. Massachusetts. Had to go do the math, because I have zero idea what .534 slugs equates to... 440 Grain arrow at approximately 270fps is one example. Would be better if you can post your arrow speed / weight because most people are going to be in the same position I was. I would not use killzones under any scenario for Elk., The rare silver-backed chevrotain, an animal that looks like a deer and is as small as a rabbit, has been found Vietnam after being lost to science for 30 years. It’s not a mouse, ..., John Deere makes the case for why agriculture and agribusiness should have a place at a consumer electronics show. Consumer tech is at an inflection point right now, with slowing g..., 11-Jun-09. Bogsucker -- 23 ft. pounds of kinetic energy is way too low for hunting moose. Most of the professional hunters recommend a minimum of 45-50 ft. pounds of kinetic energy to hunt these larger animals, and advise going higher if you can handle it., Past this distance, even the fastest arrow cannot overcome the pull of gravity, and it will begin to lose energy and elevation at a very quick rate. For instance, a 400-grain arrow that travels at 400 fps from a crossbow will drop around 93 inches (yes xe2x80x93 thatxe2x80x99s well over 7 feet!) to hit a target at 100 yards., For example, any given body has kinetic energy if it is in motion. A tensioned device such as a bow or spring, though at rest, ... How much Energy to kill a Deer? 700man; Nov 26, 2009; 2 3. Replies 35 Views 103K. Jul 18, 2013. Beluebow. B. R. Energy.

The sum equals the kinetic energy — a.k.a. KE in foot pounds — of an object in motion. ... Just as you can cleanly kill deer with a .22 Hornet, you can also kill elk with wide-cutting mechanicals and light arrows — if everything proceeds according to script ..., The arrow’s weight and construction: The combination of draw weight and arrow weight affects the kinetic energy delivered on impact. The arrow should be matched to the draw weight to optimize performance., In general, an arrow loses five feet of its kinetic energy per 10 yards after impact. So for a 40 lb bow firing out a 300 grain arrow at 230 fps for 50 yards shot from this same bow will only have 28 feet-lbs left upon impact at impact. As such, less kinetic energy is required than many hunters believe to kill a deer., Oct 12, 2020 · Seems the answer is 1300 KE when the round hits the deer. That's not at the muzzle. I don't see any PCP rifles that are any where close to that. I know people are taking deer with thier PCPs. Arkansas law says, "40-caliber, produce at least 400 ft. lbs. of energy". Guess that's a start. , A chronograph can be used to measure speed or can be obtained from the manufacturer. Once these figures are known, multi- ply velocity X velocity X total arrow weight in grains, and then divide that figure by 450,340 to obtain kinetic energy in foot-pounds. The weight of crossbow arrows is designated in grains., Kinetic energy equals velocity squared, multiplied by mass, divided by 450,240. The sum equals the kinetic energy — a.k.a. KE in foot pounds — of an object in motion. ... Just as you can cleanly kill deer with a .22 Hornet, you can also kill elk with wide-cutting mechanicals and light arrows — if everything proceeds according to script ..., What's the minimum amount of kinetic energy needed to kill a deer? Many states set minimum draw weight requirements for bowhunters to adhere to. But draw weight alone is not an indication of penetration power. There are other variables to consider, such as what arrow and broadheads are used and the distance of the shot., The Swiss's kinetic energy is 1/2 times .05 kilograms times two meters per second squared, which is .1 Joules, or half the kinetic energy of the cheddar. So we can see that at the same speed, the cheddar has more kinetic energy because it has more mass. But when the Swiss has a speed of four meters per second and the cheddar still has a speed ..., 8/29/2012. The term handgun “stopping power” generally relates various opinions about the ability of handguns to create ballistic wounds sufficient to incapacitate a target., It throws a light weight bullet, but fast enough to have the energy it needs to knock down a 250-pound deer. The average 100 grain 243 bullet has between 1100- and 1200-foot pounds of energy at 300 yards. That's where the average .223 bullet is at 50 yards. and I argue that a 223 works for deer. How much recoil does a .243 have?, johnhames. Recurves effectively kill deer with 35 to 45 ft.lbs of KE. But that is getting close to the bounce off level of energy. One of the first deer I ever shot at was with a 50# recurve, 600 grain arrows and a cut on contact broad head at 10 yds. I unluckily hit a rib, I assume crosswise., A subsonic round and a 44mag throwing 240-300gr bullets kill in very different ways. "Power" doesn't even make sense, I don't care what the kinetic energy numbers say. A sub is essentially a broadhead, if you are smart enough to choose one of the few bullets that can expand at such velocities (IMHO a broadhead is better)., Speed alone is not a good indicator of a bows ability to harvest an animal. The question you should be asking is "how much kinetic energy do I need to humanely harvest a deer?" The general answer to that is something around 45 ft/lbs. Kinetic energy is a factor of the speed and weight of the arrow. The amount of KE produced is easily …, In order to kill a deer with a single FPE, it would need to be a very large deer. The average whitetail deer weighs between 120 and 200 pounds, so it would take at least 1,200 ft-lbs of energy to kill one. That’s equivalent to about 12 FPE. So, while it is possible to kill a deer with a single FPE projectile, it’s not likely., What this data translates to is that while .410 slugs may provide sufficient energy within 50 yards, beyond that its efficacy begins to drop dramatically. In fact, according to some ballistician's recommendation of a minimum 1,000 foot-pounds of energy to ethically kill a deer, the .410 is inadequate even at the muzzle., Speed is a component in the equation, but mass affects MO and penetration much much more over speed. You will kill a deer with an arrow flying 50fps if it weighs 700, 800, 1000 grains, I don't know that number. I would be willing to bet you could get a PT at 10 yards. ... This is because kinetic energy determines the potency of the arrow being ..., Question: Two objects sliding on a frictionless surface, as represented above, collide and stick together. How much kinetic energy is converted to heat during the collision? 1/9 J 1/6 J 1/2 J 3/4 J 5/6 J. The answer is E. Show transcribed image text. There are 2 steps to solve this one. Expert-verified., The .22-250 Remington will throw a 60-grain pill at least 3,600 fps. Sighted dead-on at 200-yards, it will drop just 5.4 inches at 300-yards and still be packing 816 ft. lbs. That's 300 ft. lbs. MORE than the 30-30 Winchester with a 150-grain flat nose. A .22 caliber bullet with enough energy down range is perfectly capable of killing a deer ..., Because projectiles launched with compressed air generate substantially less terminal kinetic energy than projectiles launched with gunpowder. ... any airgun – is all about precise shot placement. Thus, the limits of the practical range for killing big game like deer and hogs humanely with the most powerful big-bore airguns, is 60-80 yards ..., We would like to show you a description here but the site won't allow us.
