In the park, several children with a total mass of 240 kg are riding a merry-go-round with a rotational inertia of 1500 Kg*ms2 and a radius of 2,2m. The average distance of the children from the axle of the meery-go-round is2.0m since they are all riding near the edge. A. What is the rotational inertia of the children about the merry-go-round? What is the total rotational inertia of the children and the merry-go-round? B. the children now move inward toward the center now their average distasnce from the axle is 0.5m. what is the new rotational inertia for the system? C. If the inital rotational velocity of the merry-go-round was 1.2 rad/s, what is the rotational velocity after the children move tot he center, igoring frictional torque.
