Acceleration, angular speed and revolutions

The tub of a washer goes into its spin-dry cycle, starting from rest and reaching an angular speed of 5.0 rev/s in 8.0 sec.

a) What is the average acceleration in radians/sec?

b) Through how many revolutions does the tub turn in that time?

c) If the lid is opened, the safety switch turns off the washer, and the tub slows to a rest after 100 revolutions. How much time does it take the tub to come to a rest?
