An electric fan is turned off, and its angular velocity decreases uniformly from 500 rev/min to 200 rev/min in 4.00 s.
(a) Find the angular accelera1ion in rev/s' and the number of revolutions made by the motor in the 4.00-s interval.
(b) How many more seconds are required fur the fan to come to rest if the angular acceleration remains constant at the value calculated in part (a)?
