Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

### Problem Statement:
The cylinder rotates about the fixed z-axis in the direction indicated. If the speed of point \( A \) is \( v_A = 3.1 \, \text{ft/sec} \) and the magnitude of its acceleration is \( a_A = 20.1 \, \text{ft/sec}^2 \), determine the magnitudes of the angular velocity and angular acceleration of the cylinder. Is knowledge of the angle \( \theta \) necessary?

### Diagram Description:
The provided diagram illustrates a cylindrical object rotating about the z-axis. The cylinder has several key features and measurements:
- The center of rotation is labeled as point \( O \).
- The cylinder's axis is aligned along the z-axis, and it is rotating with angular velocity \( \omega \).
- The radius from the center \( O \) to point \( A \) is given as 8 inches.
- The speed and acceleration of point \( A \) are respectively given as \( v_A = 3.1 \, \text{ft/sec} \) and \( a_A = 20.1 \, \text{ft/sec}^2 \).
- The coordinate system is depicted with x, y, and z axes, and point \( A \) is located at the end of the radius making an angle \( \theta \) with the y-axis.

### Part 1:
**Determine the magnitude of the angular velocity of the cylinder.**

**Given Information:**
- Speed at point \( A \), \( v_A = 3.1 \, \text{ft/sec} \)
- Radius \( r = 8 \, \text{inches} = \frac{8}{12} \, \text{ft} = \frac{2}{3} \, \text{ft} \)

**Solution Attempt (but marked as incorrect):**
The attempted solution calculates angular velocity \( \omega \):
\[ \omega = \boxed{6.48} \, \text{rad/sec} \]

_Note: The answer provided of \( \omega = 6.48 \, \text{rad/sec} \) is indicated as incorrect._

### Detailed Explanation:
1. **Calculate Angular Velocity \( \omega \):**
The relationship between linear speed \( v_A \) and angular velocity \( \omega \) is given by:
\[ v_A = \omega \cdot r
