Question

A bullet leaves a rifle with a muzzle velocity of 1042 m/s. While accelerating through the barrel of the rifle, the bullet moves a distance of 1.680 m. Determine the acceleration of the bullet (assume a uniform acceleration)​

Answer 1

Explanation:

We assume the bullet leaves from rest. So the initial velocity will be, u=0m/s

Also given, final velocity v=521m/s and distance traveled d=0.840m

Let a be the acceleration of the bullet.

Using v
