I I) A 4.2-m-diameter merry-g o-round is rotating freely with a n angular velocity of 0.80 r ad/s. Its to tal m om ent of ine rtia is 1760 kg • m2. Four people standing on the ground, each of mass 65 kg, suddenl y step onto the edge of the merry-go-round. What is the angular velocity of th e merry-go-round now? W ha t if the people were o n it initially and the n jum ped off in a radial direction (relative to the merry-go -round)?
