A 3.5-m-diameter merry-go-round is rotating freely with an angular velocity of 0.77 rad/s . Its total moment of inertia is 1760 kg⋅m2 . Four people standing on the ground, each of mass 69 kg , suddenly step onto the edge of the merry-go-round.
A) What is the angular velocity of the merry-go-round now?
B) What if the people were on it initially and then jumped off in a radial direction (relative to the merry-go-round)?
