A 4.4-m-diameter merry-go-round is rotating freely with an angular velocity of 0.90 rad. Its total moment of inertia is 1360 kg⋅m2 . Four people standing on the ground, each of mass 62 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)?

nly the final value of the answer. A merry-go-round with a moment of inertia of 6.78 x 109 kg • m2 is coasting at 2.20 rad/s. When a 87-kg man steps onto the rim, the angular velocity decreases to 20 rad/s. What is the radius in meters of the merry-go-round? Write your answer with ONE decimal place.
