A centrifuge rotor rotating at 11500 is shut off and is eventually brought uniformly to rest by a frictional torque of 1.52 .

a.If the mass of the rotor is 6.07 and it can be approximated as a solid cylinder of radius 0.0750 , through how many revolutions will the rotor turn before coming to rest?

b.How long will it take?
