Question

A bullet of mass 50 g is fired from a rifel of mass 4kg with a velocity of 35 m/s what is the recoil velocity of rifel . Solve according to 9th class

Answer 1

Since no external force acts on the rifle, the change in momentum is zero.

Mometum of rifle = Momentum of bullet.

4 x V = 0.050 x 35

V = 0.44 m/s.

This is the recoil velocity of rifle
