At t = 0 a grinding wheel has an angular velocity of 22.0 rad/s. It has a constant angular acceleration of 33.0 rad/s² until a circuit breaker trips at time t = 2.50 s. From then on, it turns through an angle 437 rad as it coasts to a stop at constant angular acceleration.

A) through what total angle did the wheel turn between t = 0 and the time it stopped in radians? B) at what time did it stop in seconds? C) what was it’s acceleration as it slowed down? In rad/s^2
At t=0 a grinding wheel has an angular velocity of 22.0 rad/s.
It has a constant angular acceleration of 33.0 rad/s² until a
circuit breaker trips at time t = 2.50 s. From then on, it turns
through an angle 437 rad as it coasts to a stop at constant
angular acceleration.
