A 5.34g bullet leaves the muzzle of a rifle with a speed of 348 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.812 m long barrel of the rifle?
Answer:- Force :
Explanation:-
Let,
Given:-
By Kinematic equation we have,
Initially, the bullet is at rest, therefore the initial velocity becomes zero,
This is the acceleration of the bullet.
According to the Newton's second law of motion we have,
This is the force exerted on the bullet while it is traveling down the 0.812 m long barrel of the rifle.
