Question
**Problem 2:**
The graph shows the x position of a small ball hooked onto a spring of spring constant 2000 N/m.

a. **What is the mass of the ball?**

b. **What is the maximum potential energy stored in the spring during the oscillations? Assume \( U = 0 \) at equilibrium.**

**Graph Explanation:**

The provided graph plots the position \( x \) (in centimeters) of a small ball against time (in milliseconds). The x-axis represents time ranging from 0 ms to 30 ms, and the y-axis represents the position \( x \) of the ball ranging from 0 cm to 40 cm. The curve depicts oscillatory motion, indicating that the ball follows a periodic back-and-forth movement due to the spring.

**Graph Details:**

- At \( t = 0 \) ms, \( x \approx 27 \) cm.
- At \( t \approx 7.5 \) ms, \( x \) reaches a peak value of \( x \approx 40 \) cm.
- At \( t \approx 15 \) ms, \( x \approx 20 \) cm which is approximately the midpoint.
- At \( t \approx 22.5 \) ms, \( x \) reaches a minimum value of \( x \approx 0 \) cm.
- The motion then continues to repeat following a sinusoidal pattern.

This periodic motion is characteristic of simple harmonic motion, a type of oscillatory motion. The spring constant provided (2000 N/m) along with this data will allow us to calculate the required physical properties such as the mass of the ball and the maximum potential energy stored in the spring.
