Problem 2: When a 3.75-kg fan, having blades 22.5 cm long, is turned off, its angular speed decreases uniformly from 11.0 rad/s to 7.20 rad/s in 6.00 s. (a) What is the magnitude of the angular acceleration of the fan? (2 pts) (b) Through what angle (in degrees) does it turn while it is slowing down during the 6.00 s? (1 pt) (c) If its angular acceleration does not change, how long after it is turned off does it take the fan to stop. (2 pts)
