A large disc has mass 2 kg and radius 0.2 m and initial angular velocity 50rad/s and a small disc has mass 4kg and radius 0.1m and initial angular velocity 200 rad/s, both rotating about their common axis. Then the common final angular velocity after discs are in contact is,

Two discs are rotating about their axes, normal to the discs and passing through the centers of the discs. Disc D_1 has 2 kg mass and 0.2m radius initial angular velocity of 50 rad s^-1 . Disc D_2 has 4 kg mass, 0.1 m radius and initial angular velocity of 200 rad^s-1 The two discs are brought in Contact face to face, with their axes of rotation coincident The final angular velocity (in rad s^-1) of the system is
