A circular disk of a moment of inertia It is rotating in a horizontal plane, about its symmetric axis, with a constant angular speed ωi. Another disk of a moment of inertia Ib 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 ωf. The energy lost by the initially rotating disc due to friction is:

1. 12Ib2It+Ibωi2

2. 12It2It+Ibωi2

3. 12Ib-ItIt+Ibωi2

4. 12IbItIt+Ibωi2
