It is your turn to keep the younger members of the family amused for half an hourwhile everyone else prepares the evening meal so you wander outside of the houseonto the concrete driveway, taking a tennis ball and a ping-pong ball with you.a) You hold both of the balls out in front of you at the same height and let go ofthem at the same time. They bounce off the concrete. Which bounces higher andwhy?b) You now place the ping-pong ball on top of the tennis ball and drop them inthis arrangement from the same height as you did previously. When the tennis ballhits the ground the ping-pong ball shoots off the top high into the air, to the delight ofthe younger children. Why did the ping pong ball do this and how high did it go?
