Question

From a rifle of mass 4 kg a bullet of mass 50 gram is fired with an initial velocity of 35 m per second calculate the initial recoil velocity of the rifle rifle

Answer 1

hence the recoil velocity of rifle is7/16m/sec

Answer 2

The impulsive force of the bullet=the impulsive force of the rifle

Mass×velocity=mass×velocity

(↑bullet↓). (↑rifle↓)

(0.05)(35)=(4)×(velocity)

1.75m/s= Recoil Velocity of the rifle
