A body of mass 10kg moving with velocity 30m/s collide with another body of mass 15kg.If the velocity of both the body are same after collision.Then find their common velocity.

The law of conservation of linear momentum will allow you to solve this problem. They apparently want you to assume that the 15 kg body is initially stationary.

M1*V1 = (M1 + M2)*V2

M1 = 10 kg

M2 = 15 kg

V1 = 30 m/s

Solve for V2.
