Asked by Samantha

At time t=0 a grinding wheel has an angular velocity of 26.0 rad/s. It has a constant angular acceleration of 25.0 rad/s^2 until a circuit breaker trips at time t = 2.50 s. From then on, the wheel turns through an angle of 440 rad as it coasts to a stop at constant angular deceleration.

Through what total angle did the wheel turn between t=0 and the time it stopped? At what time does the wheel stop? What was the wheel's angular acceleration as it slowed down?

What is your thinking on this? break the displacement and velocity in to time before t=2.5sec, and aft4er.

I don't understand the question. What's the displacement for either of those parts? What equation should I use?
