A mechanic needs to replace the motor for a merry-go-round. The merry-go-round should accelerate from rest to 1.5 rad/srad/s in 8.0 ss . Consider the merry-go-round to be a uniform disk of radius 6.0 mm and mass 19,000 kgkg. Suppose that it is supported by bearings that produce negligible friction torque. What torque specifications must the new motor satisfy?
