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.
