1. M 97 b b M P a a M 1. Find the moment of inertia around P
2. How much work to reach speed of 5.0 rad/s?
3. Assuming a constant torque, τ, how far did it rotate before it reached this speed?
4. Assuming a constant torque, τ, how long did it rotate before it reached this speed?

2. 54 Find magnitude and direction of angular acceleration
First find total torque

3. 8-4 Torque
The torque is defined as:
(8-10a) or

4. 54 Find magnitude and direction of angular acceleration
First find total torque
+ Torque --- counterclockwise
- Torque --- clockwise
Find the moment of inertia
The moment of inertia can be calculated without knowing about the torque
