Question: A helicopter rotor slows down at a constant rate from 350 revs/min to 260 revs/min in 1.5 minutes.

(a) Find the angular acceleration during this time interval. What are the units of this acceleration?

(b) Assuming the angular acceleration remains constant, how long does it take for the rotor to stop? (Measure time from the moment when speed was 350 revs/min.)

(c) How many revolutions does the rotor make between the time the angular speed was 350 revs/min and stopping?
