Many 2.5-in-diameter (6.35 cm) disks spin at a constant 7200 rpm operating speed. The disks have a mass of about 7.5 g and are essentially uniform throughout with a very small hole at the center. If they reach their operating speed 2 s after being turned on, what average torque does the disk drive supply to the disk during the acceleration?
