5. A girl with a mass of 35.0 kg rides on a merry-go-round and unlike in many sadistic physics problems, she does not get thrown off. The merry-go-round can be approxi- mated as a disk of radius equal to 2.50 m and a mass of 95.0 kg. With the girl riding on its very edge (i.e., 2.50 m from the center), the angular speed of the merry-go-round is 2.25 radians/s. What will the angular speed be if she moves to the center of the merry-go-round (i.e., her distance from the center will then be zero)? Recall that the moment of inertia of a disk is I = MR².
