### Understanding the Physics of Bouncing Balls

Have you ever wondered how long a ball dropped from a height would continue bouncing? Let's dive into this problem and find out.

We might think that a ball dropped from a height of 10 feet and rebounds to a height of 5/8 of its previous height at each bounce keeps bouncing forever since it takes infinitely many bounces. This is not true! We will examine this idea in this problem.

#### Problem Statement

**A.** Show that a ball dropped from a height of \( h \) feet reaches the floor in \( \frac{1}{4} \sqrt{h} \) seconds. Then use this result to find the time, in seconds, the ball has been bouncing when it hits the floor for the first, second, third, and fourth times:

1. **Time at first bounce**: 
   \[ \text{time at first bounce} = \_\_\_\_\_\_ \]
   
2. **Time at second bounce**: 
   \[ \text{time at second bounce} = \_\_\_\_\_\_ \]
   
3. **Time at third bounce**: 
   \[ \text{time at third bounce} = \_\_\_\_\_\_ \]
   
4. **Time at fourth bounce**: 
   \[ \text{time at fourth bounce} = \_\_\_\_\_\_ \]

**B.** How long, in seconds, has the ball been bouncing when it hits the floor for the nth time (find a closed form expression)?
   
\[ \text{time at nth bounce} = \_\_\_\_\_\_ \]

**C.** What is the total time that the ball bounces for?

\[ \text{total time} = \_\_\_\_\_\_ \]

---

By solving each part of this problem, we can understand the factors that influence the bouncing behavior and the duration of bounces. This provides a practical application of physics concepts such as gravity and motion.

Note: You may replace the placeholders with the actual calculations once you have worked through the steps.
