A washing machine is spinning at 5 rev/s at the time you open the lid and the motor disengages. The machine’s agitator in the center of the tub then begins to slow down. You observe that it makes 10 revolutions before coming to a stop. Assume that the angular acceleration is constant at all times.
a) What is the angular acceleration of the agitator in this process?
b) How long does it take the agitator to stop?
