How much kinetic energy to kill a deer.

KE = (arrow weight / 450240) x (velocity x velocity) Usually the advertised fps rating is achieved using the lightest arrow recommended for the bow. For example, a bow that uses a minimum arrow weight of 350 grains achieving 305 fps would have. (350/450240) x (305x305) = 72.3 ft/lbs of kinetic energy.How much kinetic energy do I need to shoot the 2" whitetail special? Answer: For whitetail size game we recommend that you shoot a minimum of 65 ft lb of KE in order to get maximum penetration and performance from our huge, 3 blade, 2" cut, whitetail special Broadheads. Kinetic Energy CalculatorAn 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.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 ...

This determines the arrow's penetrating ability, which results in a more effective bow kill. You measure kinetic energy through a mathematical formula. To discover your bow's kinetic energy, take the velocity squared and multiply it by the weight of your hunting arrow in grains. ... Most experts agree that deer-sized animals can be taken ...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 ...1. In proton-beam therapy, a high-energy beam of protons is fired at a tumor. The protons come to rest in the tumor, depositing their kinetic energy and breaking apart the tumor's DNA, thus killing its cells. For one patient, it is desired that a total of 0.20 JJ of proton energy be deposited in a tumor. To create the proton beam, the protons.

A kinetic bombardment or a kinetic orbital strike is the hypothetical act of attacking a planetary surface with an inert kinetic projectile from orbit (orbital bombardment), where the destructive power comes from the kinetic energy of the projectile impacting at very high speeds. The concept originated during the Cold War.. Typical depictions of the tactic are of a satellite containing a ...Normally a conical is fired at velocities between 1,200 and 1,600 feet per second (fps). A 370-grain .50-caliber conical with a 100-grain charge will have a velocity of about 1,450 fps. The muzzle energy of such a load is 1,727 ft./lbs., but at 100 yards, only 825 ft./lbs. My .58-caliber 260-grain round ball with a 100-grain blackpowder charge ...

a) Using law of conservation of momentum m1*u1 = (m1+m2)*v …. A 25,000 kg freight car is coasting at 0.650 m/s with negligible friction under a hopper that dumps 100,000 kg of scrap metal into it. What is the final velocity (in m/s) of the loaded freight car? (Enter the magnitude.) How much kinetic energy (in J) is lost?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.However, with increased speed comes greater vibration and wear and tear on the bow. To use another African example, a crossbow shooting a 500 grain arrow at 350 fps developes about 100 foot-pounds of kinetic energy, sufficient go-power to hunt Cape buffalo or elephant in a compound bow. Granted, no elephants are likely to be passing …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 ...

Mar 22, 2024. #1. I'd like to see a discussion on what is considered 'Enough' energy to effectively kill an Elk, Deer, Antelope...critter in general. I've seen folks suggest that anything over 1100ft/lbs all the way to a minimum of 1500. While looking at some Pistol data, I found that a .45ACP 230gn bullet has 369 ft/lbs of energy at the muzzle ...

One of its most popular factory loads features the 115-grain Nosler Ballistic Tip bullet with a muzzle velocity of 3,400 fps, which generates 2,952 ft.-lbs. of kinetic energy (K.E.)—comparable muzzle energy to the .30-06 and .35 Whelen. The .257 Weatherby Magnum shares the same cartridge case as both the .270 and 7mm Weatherby Magnums.

As bowhunters, we have one goal. A well executed shot & perfectly placed arrow providing a clean passthrough. I want you to read that last line once more and...Kinetic energy is a term used in the gun industry, properly used to describe the amount of energy that will potentially impart on the animal. ... (with quite a few kills on deer consequently). I have however passed through the flat cartilaginous/ thin bone part of the shoulder many times with no problems. From: Bowfreak. 05-Oct-10Fort Shaw, Montana. Aug 26, 2010. #4. Foot Pounds of energy is a VERY poor way to determine if a cartridge will be effective at harvesting a deer or not. Let me explain, I have taken literally dozens of whitetail deer out to 300 yards using a 22-250 loaded with Hornady 55 gr SP bullets loaded to 3600 fps.Energy retention as a result of heavy bullet construction and the retention of momentum can be even more of a problem in the .338 bore which has many projectiles designed specifically for Elk hunting. Furthermore, many hunters use match bullets in the .338 for long range hunting, some of which are simply hopeless on game. Projectile constructionSomeday I'd like to hunt bears with my crossbow. Maybe an elk, too...or even a moose! How much kinetic energy do I need to get that done?This is not a chann...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 ...The kinetic energy formula defines the relationship between the mass of an object and its velocity. The kinetic energy KE equation is as follows: KE = 0.5 × m × v². where: m — Mass; and; v — Velocity. With the kinetic energy formula, you can estimate how much energy is needed to move an object.

Those weighing 20-35 lbs require 35-50 foot-pounds of energy to kill, and those weighing 50-75 lbs require 80-100 foot-pounds of energy. Large game refers to animals over 75 lbs. Animals weighing up to 500 lbs require 150-250 foot-pounds of energy to kill. While animals around 1000 lbs or more require 500-700 foot-pounds of energy to kill.placed. 2500 ft/lbs is recommended for animals weighing 1500 pounds and 4000 ft/lbs + for. dangerous game for obvious reasons. The main thing is to use a bullet at or above it's designed velocity and energy so as to get the. best performance from it under ALL hunting conditions. So to sum it up if you are hunting deer.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.Find an answer to your question Lucy and her bike together have a mass of 120kg.

Part A If the mass of the second cart is m2=0.53kg, how much kinetic energy is lost as a result of the collision? Express your answer to two significant figures and include appropriate units.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 …

Energy gives us an idea of how much power there is to initiate things like bullet expansion and penetration, but does not guarantee that they will occur. It is generally recommended that a small bore (.24-.32 caliber) rifle bullet suitable for medium size (CXP2 class) game be carrying about 800 ft. lbs. of kinetic energy when it hits.

This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: A 1900.098 kg car is travelling along a road. How much kinetic energy does the car have if it were travelling at 40.0 km/h [E], and how much would it have if it were travelling at 30.0 km/h [W]?I absolutely will. A steel BB with 4.85 ft-lbs of energy is probably (I'm not breaking out lowerys' for this. I'm trying to EASE my way back into posting, lol) right around your magical 600 fps. It's also probably out a little past 65 yards at 59 degrees and sea level, and somewhere around 1.75" of gelatin penetration.Rifle rounds on the other hand have more kill (kinetic) power. This is possible even at long ranges if you have the proper shot placement. Reasons attributed to the more deadly energy for 5.56x45mm NATO cartridge include; Gas Pressure. A 5.56 mm rifle round has higher pressure gas which results from the imploding and expanding powder. This ...velocity x velocity x total arrow weight (in grains) divided by 450,240. How much do your arrows weigh in grains. How fast (in feet per second) are your arrows. to calculate your KE (kinetic Energy) Your KE = How much KE do you really need? If you're hunting deer, you don't need much at all. As long as you make a good shot, that is.Hunters aim to kill. In addition to being a Level 2 U.S. archery coach, Mark Beck is a hunter and an engineer with Plano Synergy who has experience in designing both arrows and crossbows. He makes no secret which side of the argument he's on. "I want more kinetic energy to drive that broadhead through," he said.Summary. If you don't care about hitting a target, a powerful modern crossbow can shoot as far as 500 yards. If you want to hunt, up to 80 yards is possible for a very skilled shooter, however you should stick to a maximum of 60 yards, and preferably much less than that (30-35) if you are a beginner. For target practice, everything will ...

Because there are so many factors at play, it’s hard to say with 100% certainty which arrow setups will penetrate a deer's shoulder every time. However, let's call out a few examples of modern-day arrow setups that are very likely to penetrate the scapula. Take the average male bowhunter shooting a roughly 70-pound bow, with about a 28 …

Oct 27, 2012 · Accuracy trumps kinetic energy and momentum of the arrow. You could kill any whitetail deer with a 45 lb bow shooting a 300 grain arrow with a field point. But if you don't hit the vitals it wouldn't help shooting a 500 grain arrow with a 80 lb bow and a 3" head. You might end up with a dead deer but good luck finding him.
