An old 33 1/3 rpm turntable may be approximated by a cylindrical disk of mass 0.250kg and a diameter of 31.0cm.
a.) What average torque will bring it up to operating speed in 1.50 seconds starting from rest?
b.) what net work is done on the disk in bringing it up to operating speed?
The Attempt at a Solution
Can anyone help me get started on this? We never went over torque!
