A computer hard drive rotates at 5400 revolutions per minute. Starting from rest, what torque will get the hard drive up to that speed in just 150 revolutions? The moment of inertia of the hard drive is 1.3×10^-2 kg·m^2.

I know the answer is 2.2 N.m, but I'm not sure what the steps are. Thank you in advance!
