is rotating in a horizontal plane, about its symmetry axis, with a constant angular speed 
. Another disk of moment of inertia 
is dropped coaxially onto the rotating disk. Initially the second disk has zero angular speed. Eventually both the disks rotate with a constant angular speed 
. The energy lost by the initially rotating disc to friction is
