### Physics Problem on Rotational Motion: Motorcycle Wheel Dynamics

**Problem Overview:**
Consider an **11.0 kg motorcycle wheel** shown in the figure.

![Motorcycle Wheel Diagram](#)

Assume it to be approximately an annular ring with an inner radius of \( R_1 = 0.280 \, \text{m} \) and an outer radius of \( R_2 = 0.440 \, \text{m} \). The motorcycle is on its center stand, so that the wheel can spin freely.

### Given Data:
- **Mass of the wheel**: \( 11.0 \, \text{kg} \)
- **Inner radius**: \( R_1 = 0.280 \, \text{m} \)
- **Outer radius**: \( R_2 = 0.440 \, \text{m} \)
- **Force exerted by the drive chain**: \( 2320 \, \text{N} \)
- **Radius where the force is applied**: \( 5.00 \, \text{cm} \) (or \( 0.050 \, \text{m} \))

### Questions:
**(a)** If the drive chain exerts a force of \( 2320 \, \text{N} \) at a radius of \( 5.00 \, \text{cm} \), what is the angular acceleration (in \( \text{rad/s}^2 \)) of the wheel?

\[ \boxed{\text{rad/s}^2} \]

**(b)** What is the tangential acceleration (in \( \text{m/s}^2 \)) of a point on the outer edge of the tire?

\[ \boxed{\text{m/s}^2} \]

**(c)** How long (in \( \text{s} \)), starting from rest, does it take to reach an angular velocity of \( 80.0 \, \text{rad/s} \)?

\[ \boxed{\text{s}} \]

---

### Explanation of Diagrams:
**Diagram Analysis:**
- The diagram shows a cross-sectional view of the motorcycle wheel annotated with key parameters including radii \( R_1 \) and \( R_2 \), and the point where the force \( F \) is applied.
- \( \alpha \) denotes the angular parameters
