Two particles P P\,P and Q Q\,Q have mass 0.4 kg and 0.6 kg respectively. The particles are initially at rest on a smooth horizontal table. Particle P P\,P is given an impulse of magnitude 3 N s in the direction PQPQPQ.
Find the speed of P P\,P immediately before it collides with QQQ.
Immediately after the collision between P P\,P and QQQ, the speed of Q Q\,Q is 5 m s−1^{-1}−1. Show that immediately after the collision P P\,P is at rest.
