At a grinding wheel has an angular velocity of 27.0 . It has a constant angular acceleration of 35.0 until a circuit breaker trips at time = 2.10 . From then on, it turns through an angle 438 as it coasts to a stop at constant angular acceleration.

Through what total angle did the wheel turn between and the time it stopped?

At what time did it stop?

What was its acceleration as it slowed down?
