An electric fan is turned off, and its angular velocitydecreases uniformly from 410 rev/minto 300 rev/min in 6.00 s.
(a) Find the angular acceleration in rev/s2 andthe number of revolutions made by the motor in the 6.00 sinterval. rev/s2 rev(b) How many more seconds are required for the fan to come to restif the angular acceleration remains constant at the valuecalculated in part (a)?
