An electric fan is running on HIGH. After fan has been running for 1.0 minutes, the LOW button is pushed. The fan slows down to 93.0 rad/sec in 1.89 seconds. The blades of the fan have a diameter of 6.7 meters and their deceleration rate is 4.5 rad/sec2.
1) What was the initial angular speed of the fan in rev/sec? ?i = rev/sec
