Two spheres A and B, with masses 6 kg and 2kg respectively, move towards each other on a smooth horizontal surface and collide directly. Just before the collision, the speed of A is 7 ms-¹ and the speed of B is 3 ms. Immediately after the collision, both spheres move in the same direction with the speed of B being twice that of the speed of A. (a) Show that the speed of B immediately after the collision is 7-2 ms-¹. (b) Determine the coefficient of restitution between the spheres. [3] (c) Find the magnitude of the impulse exerted by sphere A on sphere B in the collision.
