A solid disk

A solid disk of radius 23.4 cm and mass 1.45 kg is spinning at 43.1 radians per second (+ direction). A solid cylinder of radius 12.1 cm and mass 3.33 kg is spinning at 43.1 radians per second in the other direction (- direction). The cylinder is dropped into the center of the spinning disk.
