Many 2.5-in-diameter (6.35-cm) computer hard disks spin at a constant 7200 rpm operating speed. the disks have a mass of about 7.50 g and are essentially uniform throughout with a very small hole at the center.
if they reach their operating speed 2.50 s after being turned on, what average torque does the disk drive supply to the disk during the acceleration?
