A solid disk of moment of inertia 0.563 kg m is spinning about its center of mass at a rate of 10.5 rad/s on top of a frictionless table surface, An identical disk that is not rotating is carefully placed on top of the rotating one, such that their centers coincide.

Solve it correctly please.

A solid disk of moment of inertia 0.563 kg m2 is spinning about its center of mass at a rate of
10.5 rad/s on top of a frictionless table surface. An identical disk that is not rotating is carefully
placed on top of the rotating one, such that their centers coincide. If there is no external force
and no loss of mechanical energy, how fast will the two-disk system rotate?
5.25 rad/s
O 10.5 rad/s
O 21.0 rad/s
O 5.91 rad/s
