Question

A 60g bullet fired from a 5kg gun leaves with a speed of 500m/s. Find the speed with which the gun recoils.

Answer 1

Answer:

Given:

Mass of bullet, m1 = 60g=0.06kg

Velocity of bullet, v1=500m/s

Mass of gun, m2=5kg

Recoils Velocity v2

According to the law of conservation of momentum

M1*v1=m2*v2

0.06kg *500= 5*v2

V2=0.06*500/5

=6m/s.
