From then on the wheel turns through an angle of 431 rad, Ask an Expert

Academics

At time t=0 a grinding wheel has an angular velocity of 22.0 rad/s. It has a constant angular acceleration of 34.0 rad/s^2 until a circuit breaker trips at time t = 1.50 s. From then on, the wheel turns through an angle of 431 rad as it coasts to a stop at constant angular deceleration.

At what time does the wheel stop?
