Two balls of the same mass are thrown towards a wall and collide with it moving with a speed of 5 m/s.  Ball A hits the wall and rebounds with a speed of 4 m/s.  Ball B hits the wall and stops.  How does the velocity change, momentum change and impulse of Ball A compare to that of the Ball B?   1)  Each ball has the same velocity change, momentum change and impulse.   2)  Ball A has the greater velocity change, momentum change and impulse.   3)  Ball B has the greater velocity change, momentum change and impulse.   4)  Ball A has the greater velocity change and momentum change; the impulses are the same.   5)  Ball A has the greater velocity change; the momentum change and the impulses are the same.
