title: "A steel ball and a piece of clay have equal masses. They are dropped from the same height on horizontal steel platform. The ball bounces back with nearly the same speed with which it hit. The clay sticks to the platform. Choose all that is true about the ball/platform and the clay/platform systems."

# A steel ball and a piece of clay have equal masses. They are dropped from the same height on horizontal steel platform. The ball bounces back with nearly the same speed with which it hit. The clay sticks to the platform. Choose all that is true about the ball/platform and the clay/platform systems.

A rubber ball and a piece of clay have equal masses. They are dropped from the same height on horizontal steel platform. The ball bounces back with nearly the same speed with which it hit. The clay sticks to the platform. Choose all that is true about the ball/platform and the clay/platform systems.

- **A.** The rubber ball has a greater change in momentum.
- **B.** The clay has a greater change in momentum.
- **C.** The total momentum of each system increases after the collision.
- **D.** The total momentum of the system decreases after the collision.
- **E.** The momentum of each system stays the same after the collision.
