Question

A rubber ball bounces upward one-half the height that it falls each time it hits the ground. If the ball was originally dropped from a distance of 20.0 feet above the ground, what was its maximum height above the ground, in feet, between the third and fourth time it hit the ground?

Accepted Answer

The correct answer is 2.5. After hitting the ground once, the ball bounces to feet. After hitting the ground a second time, the ball bounces to feet. After hitting the ground for the third time, the ball bounces to feet. Note that 2.5 and 5/2 are examples of ways to enter a correct answer.
