Problem: At t = 0 a grinding wheel has an angular velocity of 24.0 rad/s. It has a constant angular acceleration of 3.0 rad/s² until a circuit breaker trips at t = 2.00 s. From then on it turns through 42 rad as it coasts to a stop at constant angular acceleration.

Part A: How many revolutions did the wheel make between t = 0 and the time it stopped?

Part B: At what time did it stop?

Part C: What was its acceleration as it slowed down?

I need help to find its acceleration as it slowed down.
