Question

A bullet of mass 10g is fired with a rifle .The bullet takes 0.004s to move through the barrel and
leaves it with a velocity of 400m/s. Calculate the force exerted on the bullet by the rifle.

Answer 1

Answer:

v=300 ms

−1

; u=0 ,t=0.003 s ,m=0.01 kg

Force exerted by the bullet on the rifle =

time

m(v−u)

F=1000 N
