A railway truck A of mass m and a second railway truck B of mass 4m are moving in opposite directions on a smooth straight horizontal track when they collide directly. Immediately before the collision the speed of truck A is 3u and the speed of truck B is 2u. In the collision the trucks join together. Modelling the trucks as particles, find (a) the speed of A immediately after the collision, (3) (b) the direction of motion of A immediately after the collision, (1) (c) the magnitude of the impulse exerted by A on B in the collision.
