A student throws a rubber ball against a wall. The ball has kinetic energy as it moves toward the wall. After bouncing several times, the ball eventually stops. Where did some of the ball's kinetic energy go?
Kinetic thermal and kinetic acoustic energy were dissipated
Students have three containers:
Identify each container as an open or closed system
Container A -> open
Container B-> closed
