Question 8 (4 marks) A sphere, A, of mass, ma=3m is moving with an initial speed, ua = 2u on a smooth horizontal surface. The sphere A collides with another sphere B of mass, mi = 2m travelling in the opposite direction to A, with initial speed, us=u. After the collision sphere A continues to move in the same direction with speed, u va Find: a) The speed of sphere B after the collision. (2 marks) b) The coefficient of restitution between spheres A and B. (2 marks)
