Question 288

Particles P P\,P and QQQ, of masses 2 kg and 3 kg respectively, move along the same straight line in the same direction. Before they collide, P P\,P has speed 6 m s-1 and Q Q\,Q is at rest. Immediately after the collision, Q Q\,Q has speed 3 m s-1 in the positive direction.

Find the velocity of P P\,P immediately after the collision.
