a A 4 m wide, 100 kg, revolving platform is spinning at 5 RPM, when a 30 kg child jumps onto the edge of the platform. Using Conservation of Angular Momentum: a. What is the angular momentum of the revolving platform to start? (treat it as a solid cylinder) b. How much does the platform slow down when the child jumps aboard? (treat the child as a point mass at the radial distance)
