Max (15 kg) and Maya (12 kg) are riding on a merry-go-round that rotates at a constant speed. Max is sitting on the edge of the merry-go-round, 2.4 m from the center, and Maya is sitting somewhere between the edge and the center. The merry-go-round is a solid disk with a radius of 2.4 m, a mass of 230 kg, and is rotating at a constant rate of 0.75 rev/s. The system, which includes Max, Maya, and the merry-go-round, has 8700 J of rotational kinetic energy. How far away is Maya from the center of the merry-go-round?

Can someone show how to solve this, starting with Kinematics Equations please?

. In a park, four children are riding on a merry-go-round with a radius of 2.2 m and a mass of 300 kg. The children have an average mass of 45 kg each, and they are initially each standing 2.0 m from the center of the merry-go-round. The merry-go-round is rotating at a speed of 0.25 revolutions per second. The children then move inwards towards the center of the merry-go-round, so they are standing 0.5 m from the center. What...

Three children are riding on the edge of a merry-go-round that is 105 kg, has a 1.60-m radius, and is spinning at 22.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the child who has a mass of 28.0 kg moves to the center of the merry-go-round, what is the new angular velocity in rpm? Ignore friction, and assume that the merry-go-round can be treated as a solid disk and the children as points.

A disk-shaped merry-go-round of radius 2.93 m and mass 185 kg rotates freely with an angular speed of 0.621 rev/s . A 60.4 kg person running tangential to the rim of the merry-go-round at 3.51 m/s jumps onto its rim and holds on. Before jumping on the merry-go-round, the person was moving in the same direction as the merry-go-round's rim. What is the final angular speed of the merry-go-round?
