Question 5 (20 marks) Three spheres A, B and C have masses 2 kg, 3 kg and 4 kg respectively. They are moving along the same straight horizontal smooth plane with A following B, which is following C. The initial velocities of A, B and Care 8 ms?, 4 ms 1 and 2 ms in the direction ABC. Sphere A collides with sphere B and sphere B collides with sphere C. The coefficient of restitution between A and B is 1/3 and between B and C is 1/5. a) Find the velocities of the 3 spheres after both collisions have taken place. b) Explain how you know that there will be a further collision between A and B.
