Angular speed of fan

  1. May 22, 2005 #1
    An electric fan is running on HIGH. After fan has been running of 13.2 minutes, the LOW button is pushed. The fan slows down to 98 rad/sec in 1.83 seconds. The blades of the fan have a radius of 0.62 meters and their deceleration rate is 42.3 rad/sec2.

    What was the initial angular speed of the fan in rev/sec?
