What average force acted on the bullet while it was moving down the barrel?

Although we often talk about the average force on the bullet as it moves down the barrel, in reality the force varies. It is zero as the propellant ignites – increases to a maximum as the pressure develops, then reduces as the gas expands into the growing space behind the bullet.

What average force is necessary to stop a bullet with a mass of 0.02 kg?

02 kg. So \[5.2kN\] force required to stop the bullet. Hence the correct option is D.

How do you find the average contact force?

Formula for Average Force The mass of the object multiplied by the average velocity over the definite time is equal to the average force.

What is the force of a bullet on impact?

Bullets are items that carry kinetic energy and two values should be taken into consideration when calculating the impact force. The force as joules at the muzzle, which is [bullet mass] x [bullet velocity] x2 divided by 2000.

What is the average force on the bullet?

So essentially a bullet carries a kinetic energy potential measured in the Foot/LBs in the English metric. A . 50 BMG machine gun fires a 650 gr projectile at around 3000 fps. This translates to roughly 16000 pound of force at the muzzle.

What is the force of bullet?

44 Remington Magnum with a 240-grain (0.016 kg) jacketed bullet is fired at 1,180 feet per second (360 m/s) at a 170-pound (77 kg) target.

What average force is necessary to stop a bullet of mass 20 gram?

4. 2×103N.

What average force is necessary to stop a .45 caliber bullet mass of 15 grams and speed of 300m S as it penetrates a block to a distance of 5cm?

45 caliber bullet of mass of 15 grams and speed of 300 m/s as it penetrates a block to a distance of 5 cm? Problem Answer: The average force is necessary to stop a . 45 caliber bullet is 13.5 kN.

Is average force and net force the same?

As an example if you have a two second time period in which the first second there was 2 newtons of force, and the second there was 0 newtons of force, your average force would be 1 newton per second, even though there was never 1 newton of force applied to the object. Net force is a sum value.

How much force is a bullet?

A 180-grain (12 g) bullet fired from . 357 magnum handgun can achieve a muzzle energy of 580 foot-pounds force (790 J). A 110-grain (7.1 g) bullet fired from the same gun might only achieve 400 foot-pounds force (540 J) of muzzle energy, depending upon the manufacture of the cartridge.

What is the average force that accelerates a 15G bullet?

A bullet of mass 15g leaves the barrel of a rifle with a speed of 800 m/s. If the length of the barrel is 75 cm, what is the the average force that accelerates the bullet? The bullet is accelerated by a force of 6400 N. In order to be able to determine the force that accelerates the bullet, you first need to determine the bullet’s acceleration.

How does barrel length affect the speed of a bullet?

It’s the gas pressure that is exerted on the bullet while being pushed through the barrel bore what gives the bullet its speed. The longer the barrel is, the greater velocity (and therefore energy) the bullet obtains—as E K = 1 2 m v 2 (kinetic energy).

How fast can a bullet penetrate a mud wall?

Block hackers from your network, in one swift motion. Design a flexible, stronger access policy playbook around user and device authentication. A bullet of the mass of 30g moving with a velocity of 400m/s penetrate 10cm into a mud wall. What is the average force exerted by the wall on the bullet?

What is the kinetic energy of a heavy bullet?

The longer the barrel is, the greater velocity (and therefore energy) the bullet obtains—as E K = 1 2 m v 2 (kinetic energy). As you can see, the bullet energy rises much more with the velocity (with velocity square) than with mass (and bullets are not that heavy).
