What was its acceleration as it slowed down

Reference no: EM13336068

At t = 0 a grinding wheel has an angular velocity of 25.0 rad/s. It has a constant angular acceleration of 21.0 rad/s2 until a circuit breaker trips at t = 1.81 s. From then on, it turns through 432 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?

rad

(b) At what time did it stop?

rad/s2
