An electric fan is turned off, and its angular velocity decreases uniformly from 550 rev/min to 180 rev/min in a time interval of length 4.30 s.
a.) find the angular acceleration in revolutions per second per second.
= -1.43 rev/s^2
b.) find the number of revolutions made by the fan blades during the time that they are slowing down in part a.
= rev
c.) how many more seconds are required for the fan to come to rest if the angular acceleration remains constant at the value calculated in part a?
= s
