Homework Help: physics

A thin disk, mounted on a frictionless vertical shaft of negligible rotational inertia, is rotating at 495 revolutions per minute. An identical disk (that is not initially rotating) is dropped onto the first disk. The frictional force between the disks causes them to rotate at a common angular velocity. Find this common angular velocity.
