1. A disk whose moment of inertia is 2 kgm2 is rotating at 120 rad/s. This disk is pressed against a similar disk (with the same inertia) that is able to rotate freely, but initially at rest. The two disks stick together and rotate as a unit. (a) Find the final angular velocity of the combination. (b) How much energy was lost to friction when the disks were brought together?

A disk with moment of inertia 9.15 × 10−3 kg∙m^2 initially rotates about its center at angular velocity 5.32 rad/s. A non-rotating ring with moment of inertia 4.86 × 10−3 kg∙m^2 right above the disk’s center is suddenly dropped onto the disk. Finally, the two objects rotate at the same angular velocity ?? about the same axis. There is no external torque acting on the system during the collision. Please compute the system’s quantities below. 1. Initial angular momentum ??...
