Andy (whose mass is 31.0 kg) and Ollie (whose mass is 23.2 kg) are standing at the center of a 135 kg merry-go-round of radius 1.44 m that is already spinning at 39.1 rpm. They proceed to walk in opposite directions toward the edge of the merry-go-round. If Andy reaches the edge while Ollie is halfway between the center and the edge, what will be the new angular velocity of the merry-go-round (in rpm)? For simplicity's sake, you may treat the children as point masses and the merry-go-round as a disk.
If, at the end of the previous question, a third child suddenly jumps onto the edge of the merry-go-round, what happens to its motion?

Two children (m = 31.0 kg each) stand opposite each other on the edge of a merry-go-round. The merry-go-round, which has a mass of 1.78 ✕ 102 kg and a radius of 1.2 m, is spinning at a constant rate of 0.48 rev/s. Treat the two children and the merry-go-round as a system. (a) Calculate the angular momentum of the system, treating each child as a particle. (Give the magnitude.) (b) Calculate the total kinetic energy of the system. (c)...

A boy of mass 35.2 kg is standing on the edge of a merry-go-round which is at rest.
A boy of mass 35.2 kg is standing on the edge of a merry-go-round which is at rest. The merry-go-round is a flat disk of mass 59.3 kg and radius 2.3m (the moment of inertia of a cylinder is ½ mr^2 ), turning on a frictionless pivot. The boy starts to walk around the edge of the merry-go-round in the clock-wise direction (when viewed from the top). When the boy is moving at 2.4 m/s relative to the merry-go-round: a....
