The disk on the bottom has a rotational inertia of I0 and is spinning clockwise on a horizontal surface having negligible friction at an angular speed of 3Ο0 . The top disk is then dropped directly on top of the bottom disk. The top disk has a rotational inertia of I0 and was initially spinning counterclockwise at an angular speed of Ο0 . If the initial total kinetic energy of the two-disk system was E0 , what will the kinetic energy of the system be once the objects reach a common angular speed?
