What is the velocity of a bullet through a barrel?
A bullet leaves a rifle with a muzzle velocity of 521m/s. While accelerating through the barrel of the rifle, the bullet moves a distance of 0.840m. Determine the acceleration of the bullet (assume a uniform acceleration).
How do you calculate the acceleration of a 9mm bullet?
s is the barrel length. Since acceleration is the desired value, the derived formula is this: When fired from a Beretta 92S, the standard issue US Army pistol, a 9 mm Parabellum bullet has a muzzle velocity of 335 m/s. With its 127 mm barrel length, the bullet’s acceleration is calculated to be 4.4 × 10 5 m/s 2.
What is the acceleration of a 127mm bullet?
With its 127 mm barrel length, the bullet’s acceleration is calculated to be 4.4 × 10 5 m/s 2. The acceleration of a bullet depends largely on the gun from which it is fired, along with the intent of the user.
What is the 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. You know what the length of the gun barrel and what the bullet’s exit velocity are, which means that you can write
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).
What happens if you drop a bullet in the desert?
Even in a barren desert there are high and low spots, and before the dropped bullet reaches the ground the fired bullet is very likely to hit one of the high spots. Edit – Looking back at this old answer, I just realized to my shame that I’ve neglected the curvature of the Earth!
