Let us assume that we have a homogeneous disc (flywheel) of a mass M=10m and radius R. There is a fly called Ľubo of a mass m sitting on the flywheel at a distance 0.75R from the center of the disc, while the disc (together with Ľubo) is rotating with an angular frequency ω0=1.20 rad·s⁻¹. Ľubo's friend Slavo, who has the same mass as Ľubo, suddenly sits at the edge of the disc, while he had zero angular momentum with respect to the axis of rotation of the disc. Assume that both flies are point masses and that the system (the flywheel + flies) is not subjected to any external torques. What is the angular frequency of the disc after Slavo sits on it?
