A centrifuge rotor rotating at 9300 rpm is shut off and is eventually brought uniformly to rest by a frictional torque of 1.66 m⋅N. If the mass of the rotor is 4.58 kg and it can be approximated as a solid cylinder of radius 0.0440 m, through how many revolutions will the rotor turn before coming to rest? Express your answer to three significant figures.   How long will it take? Express your answer to three significant figures and include the appropriate units.
