Bouncing Balls
A ball bounces back 0.5 times the dropped distance. If the ball was dropped
at 10 m, find the total distance travelled by the ball from the time it was
dropped until it hits the ground for the third time.
Step 1. What is the distance between the ball and the ground before the drop of
the ball?
Step 2. What is the distance travelled by the ball as it bounces up the first time
and hits the ground?
Step 3. What is the distance travelled by the ball as it bounces up the second
time and hits the ground?
Step 4. What is the total distance travelled by the ball?
