Amerry-go-round can be modeled as a solid disk of radius r and mass m. initially, it is rotating on a sturdy frictionless axle with angular velocity ω0 . a rock of mass m is dropped vertically onto the merry-go-round and it sticks to the surface at a radius r from the center. what is the final angular velocity ω of the merry-goround + rock system?

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
