What must be the initial angular speed, of the top disk be so that when it is dropped onto the bottom disk the final angular speed of the disks is equal in magnitude to the initial angular speed of the lower disk ω1 but opposite in direction? Note: the moment of inertia of a disk of mass M and radius R about an axis through its center and perpendicular to the disk is = 1 2 R 2
