Question

From a rifle of mass 4kg , a bullet of mass 50g js fired with an initial velocity of 35m/s . calculate the intial recoil velocity of the rifle.​

Answer 1

Answer:

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.

Answer 2

Answer:

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

Momentum of rifle=Momentum of bullet

4×V=0.050×35

V=0.44 m/s

This is the initial recoil velocity of the rifle.
