A centrifuge rotor rotating at 9500 rpm is shut off and is eventually brought uniformly to rest by a frictional torque of 1.93 m⋅N . If the mass of the rotor is 4.69 kg and it can be approximated as a solid cylinder of radius 0.0600 m , through how many revolutions will the rotor turn before coming to rest? How long will it take? Express your answer to three significant figures and include the appropriate units.
