Two children, A (mass 25 kg ) and B (mass 50 kg ), are playing on a merry-go-round (which you can assume is a solid disk with mass 225 kg and radius 1.5m). Assume that any friction on the axle of the merry-go-round is negligible. (A) A starts spinning the merry-go-round, giving it an angular velocity of 7 rad/s, then she stops pushing it. B runs with a speed of 6 m/s directly toward the center of the merry-go-round....
