A disk of radius .3 meters and mass of .5kg is held over another disk of radius .5 meters and mass 1 kg which is rotating in a horizontal plane at a rate of 15.92 rev/sec. The top disk is released and drops onto the bottom disk (centers align).
a) What is the final angular velocity (in rev/sec) of the two disks?
b) What was the change in rotational energy of the two-disk system?
