Question

A gun having mass 20kg fires a bullet of mass 400g with a velocity of 100m/s What will be the recoil velocity of the gun

Answer 1

Answer:

2 m/s

Explanation:

m1(gun)=20 kg

m2(Bullet)=400 g=0.4 kg

v2(Velocity of bullet)=100 m/s

According to conservation of linear momentum,

m1v1=m2v2

v1=40/20

v1=2 m/s
