2 1. A particle A of mass 3m and a particle B of mass m are moving along the same straight line on a smooth horizontal surface. The particles are moving in opposite directions towards each other when they collide directly. Immediately before the collision, the speed of A is ku and the speed of B is u. Immediately after the collision, the speed of A is v and the speed of B is 2v. The magnitude of the impulse received by B in the collision is 3 2 mu. (a) Find v in terms of u only. (3) (b) Find the two possible values of k.
