Problem
Two smooth spheres A and B of masses 0.20kg and 0.30kg respectively lie in contact on a horizontal friction-free track. Sphere A is moving toward B with a speed of 3.0m s−1 while B is at rest. The coefficient of restitution for their collision is 0.90. Just beyond B is a rigid vertical wall. The coefficient of restitution for the collision between B and the wall is 0.80.
(i) Calculate the speeds of A and B immediately after their mutual collision.
(ii) Determine the speed of B just after it rebounds from the wall.
