A 4.4-m-diameter merry-go-round is rotating freely What is the angular velocity of the merry-go-round now? with an angular velocity of 0.85rad/s. Its total moment of inertia is 1380 kg⋅m2. Four people Express your answer using three significant figures. standing on the ground, each of mass 68 kg, suddenly step onto the edge of the merry-go-round. ω=[rad/s Part B What if the people were on it initially and then jumped off in a radial direction (relative to the merry-go-round)? Express your answer using two significant figures.
