Solve the all parts of given question:

Question: When a 2.75-kg fan, having blades 18.5 cm long, is turned off, its angular speed decreases uniformly from 10.0 rad/s to 6.30 rad/s in 5.00 s.

Question I: What is the magnitude of the angular acceleration of the fan?

Question II: Through what angle (in degrees) does it turn while it is slowing down during the 5.00 s?

Question III: If its angular acceleration does not change, how long after it is turned off does it take the fan to stop.
