Question

Suppose a ball is dropped fromca height of 6ft. It bounces back up but time it bounces, it reaches only 7/10 of its pervious height. What is the total of each height that the ball reaches after 5 bounces

Answer 1

1st bounce 7/10 * 6 = 42/10 = 21/5

2nd bounce 7/10 * 21/5 = 147/50

3rd bounce 7/10 * 147/50 = 1029/500

4th bounce 7/10 * 1029/500 = 7203 / 5000

5th bounce 7/10 * 7203/5000 = 50421/50000 = 1.00842
