Find what was the acceleration as it slowed down

Reference no: EM13545291

At a grinding wheel has an angular velocity of 27.0 rad/s . It has a constant angular acceleration of 25.0 rad/s^2 until a circuit breaker trips at time t = 1.70 s. From then on, it turns through an angle 439 rad as it coasts to a stop at constant angular acceleration.

1) Through what total angle did the wheel turn between t=0 and the time it stopped? (answer in rad)

2) At what time did it stop?

3) What was the acceleration as it slowed down? (answer in rad/s^2)
