Question
### Analysis of Centripetal Force in Shot Put

**Problem Statement:**
Draw the acceleration vector for the shot put and the forces acting on it.

**a. Assumptions:**
- The chain is considered massless.

**b. Calculation of Centripetal Force:**
- Conditions:
  - The shot put completes 50 revolutions per minute.
  - Mass of the shot put, \( m = 5 \, \text{kg} \).
  - Radius of the circular path, \( r = 1.5 \, \text{m} \).

**c. Forces and Motion:**
- **Inquiry:**
  - Identify the force responsible for keeping the shot put on its circular path, preventing it from moving along a tangent.
  - Determine the relationship between this force and the centripetal force.

### Diagram Explanation:

**Figure 7-15 Description:**
- The diagram illustrates a person performing a shot put motion.
- The person is holding a chain connected to a shot put, which is swung in a circular path.
- Yellow dashed arrows represent the direction of the centripetal force toward the center of the circle.
- Gray dashed lines might indicate the path if the shot put were to fly off tangentially.

This illustration and breakdown assist in visualizing and understanding the centripetal force concept, which is crucial in circular motions such as shot put dynamics.
