# When a fan is turned off, its angular speed decreases from \( 10 \) \( \text{rad/s} \) to \( 6.3 \) \( \text{rad/s} \) in \( 5.0 \) \( \text{s} \). What is the magnitude of the average angular acceleration of the fan?

When a fan is turned off, its angular speed decreases from \( 10 \) \( \text{rad/s} \) to \( 6.3 \) \( \text{rad/s} \) in \( 5.0 \) \( \text{s} \). What is the magnitude of the average angular acceleration of the fan?

- **A.** \[1.2 \text{ rad/s}^2\]    
- **B.** \[0.86 \text{ rad/s}^2\]
- **C.** \[0.74 \text{ rad/s}^2\]
- **D.** \[11 \text{ rad/s}^2\]
- **E.** \[0.37\text{ rad/s}^2\]
