Two children, each with a mass of 24.6 kg, are at fixed locations on a merry-go-round (a disk that spins about an axis perpendicular to the disk and through its center). One child is 0.78 m from the center of the merry-go-round, and the other is near the outer edge, 2.79 m from the center. With the merry-go-round rotating at a constant angular speed, the child near the edge is moving with translational speed of 11.0 m/s. (a) What is...
