At t=0 a grinding wheel has an angular velocity of 24.0 rad/s . It has a constant angular acceleration of 27.0 rad/s2 until a circuit breaker trips at time t = 2.40 s . From then on, it turns through an angle 430 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?

3. At t-0, angular velocity of a wheel is 24 rad/s, and its angular acceleration is 30 rad/s. (i) How much angle does the wheel turn through after 2 seconds of rotation? (ii) At t-2 sec., the wheel suddenly begins to undergo angular deceleration (negative angular acceleration) of 8.16 rad/s'.

A machinist turns on the power on to a grinding wheel at time t = 0s. The wheel accelerates uniformly from rest for 10s and reaches the operating angular speed of 58 rad/s. The wheel is run at that angular velocity for 30s, and then power is shut off. The wheel slows down uniformly at 1.4 rad/s^2 until the wheel stops. What is the total number of revolutions made by the wheel in this situation ? A machinist turns on...
