Question
**Title: Analyzing Motion in a Tether Ball System**

**Introduction:**
In this study, we explore the dynamics of a tether ball of mass \( m \) attached to a vertical pole by a rope of length \( L \). Our goal is to determine the angle \( \theta \) that the rope makes with the pole as a function of the ball's speed \( v \), as well as the variables \( m \), \( L \), and \( g \) (acceleration due to gravity).

**Free-Body Diagram:**

The free-body diagram illustrates the forces acting on the tether ball. The primary forces include:
- Gravitational force \( mg \) acting downward.
- Tension \( T \) acting along the rope.
- Centripetal force required to maintain circular motion, acting horizontally towards the pole.

**Mathematical Analysis:**

We need to derive a function that represents the angle \( \theta \) in terms of \( v \), \( m \), \( L \), and \( g \). The balance of forces and the conditions for circular motion need to be incorporated into the analysis.

**Questions:**

1. **If the mass of the ball was twice as large, what would happen to \( \theta \)?**
   - Consider how increasing the mass \( m \) affects the balance of forces and consequently the angle \( \theta \).

2. **If \( v = 0 \, \text{m/s} \), what should \( \theta \) equal? Does your function agree with this observation?**
   - Analyze the scenario where the ball is at rest and how this reflects in the angle \( \theta \).

3. **If \( v = \infty \), what should \( \theta \) equal? Does your function agree with this observation?**
   - Evaluate the theoretical implications of an infinitely fast-moving ball and how \( \theta \) approaches a certain limit.

This exercise provides a comprehensive understanding of the interplay between forces and motion in a system, fostering deeper insights into classical mechanics.
