Explanation:
Each time the ball bounces, it reaches half the height of the previous bounce.
On the first bounce, the ball reaches a height of 10/2 = 5 feet.
On the second bounce, the ball reaches a height of 5/2 = 2.5 feet.
On the third bounce, the ball reaches a height of 2.5/2 = 1.25 feet.
On the fourth bounce, the ball reaches a height of 1.25/2 = 0.625 feet.
Therefore, the ball reaches a height of 0.625 feet on the fourth bounce.
