Two particles P and Q of masses 0.2 kg and 0.3 kg respectively are free to move in a horizontal straight line on a smooth horizontal plane. P is projected towards Q with speed 0.5 m s−1. At the same instant Q is projected towards P with speed 1 m s−1. Q comes to rest in the resulting collision. Find the speed of P after the collision. [3]
