Place a cardboard box on a smooth tile or wood floor. Practice rolling a basketball or soccer ball at different speeds and allowing the ball to collide with the box. Observe the motion of both the box and the ball just after the collision.
a. How do the results of the collision vary for different speeds of the ball (slow, medium, fast)?
b. If we increase the weight of the box by placing books inside, how do the results of the collision change for the cases in part a? c. Can you explain your results using conservation of momentum?
