Question
**Pendulum and Bullet Dynamics Analysis**

**Problem Statement:**

A bullet of mass \( m \) and speed \( v \) is fired at an initially stationary pendulum bob. The bullet passes through the bob and exits with a speed of \( \frac{v}{7} \). The pendulum bob is attached to a rigid pole of length \( L \) and has negligible mass. Determine the minimum speed \( v \) required for the pendulum bob to barely swing through a complete vertical circle.

**Key Variables:**

- \( m \): Mass of the bullet
- \( v \): Initial speed of the bullet
- \( \frac{v}{7} \): Speed of the bullet as it exits the bob
- \( L \): Length of the rigid pole
- \( M \): Mass of the pendulum bob

**Diagram Explanation:**

- **Bullet Path**: Initially directed towards the pendulum bob with velocity \( v \).
- **Pendulum Bob**: Represented as a circle with mass \( M \).
- **Pendulum Arc**: Dashed line showing the bob's path for a complete vertical circle.
- **Velocity Change**: Bullet's velocity decreases from \( v \) to \( \frac{v}{7} \).

**Question:**

What is the minimum value of \( v \) needed for the pendulum bob to complete the vertical circle?

**Interactive Component:**

- **Input Box**: Allows you to calculate and enter the minimum speed \( v \).

Understanding the interplay of momentum and energy conservation principles will aid in solving this problem.
