Problem
A 0.20 kg ball traveling horizontally to the right strikes a 0.60 kg block initially at rest on a frictionless surface. After an elastic head-on collision, the ball reverses direction and moves to the left at 2.0 m/s while the block moves to the right at 2.0 m/s. Determine the ball’s speed just before the collision.
