Physics Q. A merry-go-round comprises a wooded disk of radius R=2 meters and rotational inertia 148kg·m2 . It rotates with an angular velocity of 2.5rad/s, with a small (point-like!) child of mass 10kg at its center. The child then crawls to the outside rim. What is the the angular velocity now?____rad/s please explain how to solve for this.

Two disks are mounted (like a merry-go-round) on low-friction bearings on the same axle and can be brought together so that they couple and rotate as one unit. The first disk, with rotational inertia 3.25 kg m2 about its central axis, is set spinning counterclockwise (which may be taken as the positive direction) at 181 rev/min. The second disk, with rotational inertia 7.95 kg.m2 about its central axis, is set spinning counterclockwise at 879 rev/min. They then couple together. (a)...

A disk-shaped merry-go-round of radius 2.53 m and mass 185 kg rotates freely with an angular speed of 0.601 rev/s . A 55.4 kg person running tangential to the rim of the merry-go-round at 3.11 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?
