A ring (mass 2 M, radius 2 R) rotates in a CCW direction with an initial angular speed 2 w. A disk (mass 4 M, radius 2 R) rotates in a CW direction with initial angular speed 2 w. The ring and disk "collide" and eventually rotate together. Assume that positive angular momentum and angular velocity values correspond to rotation in the CCW direction. What is the initial angular momentum L; of the ring+disk system? Write your answer in terms of MR²w. 8 MR²w Remember that L¡ (system) = L; (ring) + L¡ (disk), where L = Iw for each object. Submit Answer Incorrect. Tries 2/3 Previous Tries What is the final angular velocity wf of the ring+disk system? Write your answer in terms of w. -0.67 W Remember that L¡ = Lf = Ifwf. To solve for wf, you will use L₁ from above and will need to find If of the ring+disk system. Submit Answer Incorrect. Tries 1/3 Previous Tries
