Solution: At t=0 a grinding wheel has an angular velocity of 26.0 rad/s . It has a constant angular acceleration of 31.0 rad/s2 until a circuit breaker trips at time t exttip{t}{t}= 2.10 s. From then on, it tur

At t=0 a grinding wheel has an angular velocity of 26.0 rad/s . It has a constant angular acceleration of 31.0 rad/s^{2} until a circuit breaker trips at time t exttip{t}{t}= 2.10 s. From then on, it turns through an angle 436 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?

b) At what time did it stop?

c) What was its acceleration as it slowed down?
