A ring (mass 4 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 Lj of the ring+disk system? Write your answer in terms of MR2W. MR2W Submit Answer Tries 0/3 What is the final angular velocity wf of the ring+disk system? Write your answer in terms of w. Submit Answer Tries 0/3

A child with a mass of 50 kg is on a circular frictionless platform with a mass of 100 kg. Treat the platform as a solid cylinder. The platform is initiallyrotating at a rate of 5 rmp (0.52 rad/s). The inner radius of the platform (where the child starts) is 2.0 m. The outer radius is 4.0 m.a. Determine the initial angular momentum of the system in kgm2/s. b. If the child moves from the inner to the outer radius, determine the new angular velocity of the system. c. While at the outside radius, the child catches a 2.0 kg ball travelling at 10 m/s perpendicular to the radius. Determine the final angularmomentum of the system.
