Answer to Question #36504 in Mechanics | Relativity for Quamrul islam

Question

Particle P has mass 3 kg and particle Q has mass 2 kg. The particles are moving in
opposite directions on a smooth horizontal plane when they collide directly. Immediately
before the collision, P has speed 3 m s –1 and Q has speed 2 m s –1. Immediately after the
collision, both particles move in the same direction and the difference in their speeds is
1 m s –1.
(a) Find the speed of each particle after the collision.
(5)
(b) Find the magnitude of the impulse exerted on P by Q
