Find the angular acceleration in rev/sz. An electric fan is turned off, and its angular velocity decreases uniformly from 450 rev/min to 160 rev/min in a time interval of length 4.35 s . a= -1.11 rev/s? Previous Answers Correct v PartB Find the number of revolutions made by the motor in the time interval of length 4.35 s . N = 221 rev Previous Answers Correct v PartC 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? Vol & O =m
