How is foot pounds of energy measured for bullet impact?

It can be projected by using the formula E= MV2 divided by 450400.

E is the energy in foot lbs

M is mass of bullet in grains

V2 is velocity in feet per second, squared.

It can also be directly measured by taking a known weight, shooting it, and measuring the movement of the weight. This is known as a ballistic pendulum, and is not often used today.

What is the speed of a 380 acp bullet falling straight down?

Falling, and not tumbling end over end, the bullet will accelerate (due to gravity) at 32 ft per second- per second- until it reaches the terminal velocity- limited by air resistance- around 300 mph. If tumbling end over end, more air resistance, less speed- about 225 mps MAXIMUM.

Why are bullets fast?

Bullets are fast because they are propelled by the force created by the exploding gunpowder in a firearm. This rapid expansion of gases generates high pressure that pushes the bullet out of the barrel at a high velocity.

How far can a bullet travel accurately?

The accurate range of a bullet depends on factors such as the type of firearm and bullet used, weather conditions, and the skill of the shooter. Typically, most handgun bullets have an effective range of up to 50-100 yards, while rifle bullets can be accurate up to several hundred yards or even over a mile for some high-powered rifles.

How far does a bullet travel went shot into the air?

Depends. The caliber of the cartridge, the weapon that fires it, and the angle (straight up, or tilted to one side?) all all variables that will affect how far (or how high) a bullet will go. No one answer for your question- sorry-

EDITED AND ADDED: But here's a ballpark figure. If you take a large-caliber military or big game hunting rifle and shoot it into the air on a calm day with the barrel pointed about 35 degrees above horizontal, the bullet will reach about one mile (roughly 5000 feet) in altitude above the ground at the peak of its arc, and it will land on the ground (or water) about 3 miles away. It will land with a lot less speed then when it began its trip, but it will still be dangerous.

If you fire the bullet straight up into the sky, it could go up to 10,000 feet altitude ---roughly 2 miles above ground level. That's why military aircraft consider any altitude below 10,000 feet to be "within range" from small arms fire from the ground. Above 10,000 feet they're safe from regular rifles and hand-carried machineguns, but bigger cannons can still reach them.

How far will a 9mm 115grain bullet travel?

The distance a 9mm 115grain bullet can travel depends on factors such as the angle of firing, speed at which it was shot, and the surrounding environment. On average, a 9mm bullet can travel up to 1.5 to 2 miles in ideal conditions.

How can a bullet ricochet off water?

The speed of the bullet at the time it leaves the chamber, is so high, that i can - when hitting water ( at the right angle ) skip.
If you hit water at high speed, it will feel way harder than hitting it with low speed.

For example, if you want to skip stones on water, you can't throw the stone slowly, you will have to give the stone some speed - or else it wont skip.

Can a bullet fire from body heat?

No, it cannot. The maximum amount of heat that a human body can generate at the skin level is around 110 degrees fahrenheit. This is far below the temperature range which would cause spontaneous ignition of the propellant in a modern bullet. Even black powder won't ignite at that low a temperature.

It is possible for a bullet to discharge by the force of a body falling on it, but that is extremely unlikely.

(and remember, when you say "bullet", what you really should say is "cartridge" - the "bullet" is only the lead/steel portion being expelled out the front, while "cartridge" includes the brass body and propellant as well).

What is the velocity of a 22 magnum bullet?

The velocity of a .22 Magnum bullet typically ranges from 1,500 to 2,000 feet per second (fps), depending on the specific load and barrel length.

A 5 g bullet is fired from a 5000g gun If the bullet leaves the gun going 800MS with what speed does the gun recoil?

Using the principle of conservation of momentum, we can calculate that the gun will recoil at 0.08 m/s in the opposite direction of the bullet. The total momentum of the gun and bullet before firing is equal to the total momentum after firing.

How long till a bullet loses momentum?

The rate at which a bullet loses momentum depends on various factors such as air resistance and the specific characteristics of the bullet. In general, a bullet will lose momentum relatively quickly due to air drag, but if fired in a vacuum, it could travel for several kilometers before losing all its momentum.

How long will a 9mm bullet travel before it loses power?

All bullets "begin losing power" as soon as they leave the barrel- and continue to lose power until they stop. Firearms have a maximum range- how far can the bullet be driven- and a maximum effective range- How far can I HIT a target consistently with this gun/cartridge. Most 9mm pistols have a maximum range of about 900 yards- but at that distance, you cannot reliably hit anything except the Earth. An average max effective range is about 75 yards.

What is the drop on a 180 grain bullet at 200 yards?

The drop of a 180 grain bullet at 200 yards depends on the muzzle velocity and ballistic coefficient of the specific ammunition being used. Generally, a 180 grain bullet fired from a typical hunting rifle with a muzzle velocity around 2,700 fps may drop around 5-7 inches at 200 yards when sighted in at 100 yards.

How long does it take for a bullet fired into the air to come down?

The time it takes for a bullet fired into the air to come back down depends on the bullet's initial velocity, weight, and aerodynamic properties. In general, it can take anywhere from 30 seconds to over a minute for a bullet to fall back to the ground. However, firing a bullet into the air is extremely dangerous and can cause harm or even death when it falls back down.

Why is a subsonic bullet loud?

They are actually quieter than supersonic bullets. When a gun is fired, noise comes from 3 sources- the main one being the sudden blast of gasses that are released from the muzzle as the bullet leaves. That still exists with subsonic bullets- they are just traveling slower than the speed of sound (ABOUT 1200 feet per second) The second part of the noise is from the bullet breaking the sound barrier- a high pitched CRACK sound. Subsonics do not do that. Third part of the sound is from the action of the firearm extracting the fired cartridge, and loading a new one.

What happens when a bullet hits a rubber sheet?

When a bullet hits a rubber sheet, the rubber will absorb some of the bullet's kinetic energy. The rubber sheet will stretch and deform, creating a bulge around the impact area. The bullet's force will eventually be dissipated through the material, causing the rubber to return to its original shape.

Why are bullets fired into a gel tank in a forensics ballistic lab?

Bullets are fired into a gel tank in a forensics ballistic lab to simulate the impact of a bullet on human tissue. The gel, usually ballistic gelatin, has similar density and consistency to human tissue, allowing investigators to study the behavior of the bullet upon impact. This helps in determining the trajectory, penetration depth, and potential damage caused by a fired bullet.

What is the flight of a bullet?

The flight of a bullet is the path it follows after being fired from a firearm. This path is influenced by factors such as gravity, air resistance, wind speed, and the angle at which the gun is fired. Bullets typically travel in a parabolic trajectory, rising and then falling as they move towards the target.

Why do the bullet and the capsule drop at the same time when the gun fires?

Your question is ambiguous, assuming by capsule you mean the shell casing then this is also not the case in every weapon.

Shell casings are ejected when the weapon is fired if it is an automatic or semi-automatic weapon.

Revolvers, for instance, do not eject the spent cartridges.

What is the distance a 357 magnum bullet will travel?

The distance a .357 Magnum bullet can travel depends on factors such as the specific load, barrel length, and angle of fire. On average, a .357 Magnum bullet can travel up to 1 to 1.5 miles if fired horizontally. However, it will lose velocity and energy over distance, decreasing its lethality.

An observer stands 26m behind a marksman practicing at a rifle range The marksman fires the rifle horizontally the speed of the bullet is 790 ms air temperature is 20C How far does each rilfe travel?

There is only one rifle described in the question and it travels 0 m. nice try.

The whole question is shown below:

An observer stands 26 m behind a marksman practicing at a rifle range. The marksman fires the rifle horizontally, the speed of the bullets is 790 m/s, and the air temperature is 20°C. How far does each bullet travel before the observer hears the report of the rifle? Assume that the bullets encounter no obstacles during this interval, and ignore both air resistance and the vertical component of the bullets' motion.

Define trAjectory of the bullet velocity of the bullet velocity?

Bullet trajectory is the path the bullet travels once it leaves the barrel. Bullets travel on a long arch and cross the line of sight twice. Once shortly after leaving the barrel and once again on target assuming the sights are properly zeroed. This is the trajectory of the bullet. Bullet velocity is the speed at which the bullet is traveling along it's trajectory.

What is velocity of 22 cal bullet?

Depends on WHICH 22 cartridge, and whether fired from a rifle or a pistol. A .22 BB cap from a pistol may have a muzzle velocity of 700 feet per second. .22 LR may range from 1000 fps to 1750 fps. Rifles will have a higher velocity than a pistol. PS- not all .22 caliber bullets are fired from rimfire cartridges. I shoot a .220 Swift, a centerfire rifle. It uses a large cartridge, firing a small bullet- at over 4000 fps

If you shot a bullet in to the air could the bullet kill you on its way down?

Yes, a bullet shot into the air can come down with enough force to cause serious injury or death. This is known as a "falling bullet" or "stray bullet" phenomenon, and it is important to never shoot a firearm into the air as the bullet can still retain lethal velocity when descending.

How much pressure on a bullet primer to make it go off?

The pressure required to ignite a bullet primer typically ranges from 25,000 to 35,000 pounds per square inch (psi). This pressure is generated by the firing pin striking the primer cup, causing it to crush the priming compound and ignite, subsequently firing the cartridge.
