1) A buffing wheel is connected to the shaft of a motor. When the motor is switched on, it takes the motor 6.1 seconds to rotate at 3602 cycles per minute. When the motor is switched off it takes the motor 69.8 seconds to stop. Assuming a uniform time rate of change of the angular velocity, when the working motor is switched off, how many cycles does it do to stop?
