Objects A and Care made of different materials, with different "springiness", but they have the same mass and are bot initially at rest. When ball B collides with object A, the ball ends up at rest. When ball B collides with object C, the ball rebounds to the left. Compare the velocities of A and after the collisions. Is greater, equal to, or less than vc? Justify your answer. Before: After: BO- А VO ma = mc BOC pv
