17. A 25.0 kg girl stands on the edge of a merry-go-round that is turning with an angular speed of 0.750 rad/s. The merry-go-round has a radius of 2.50 m and a moment of inertia of 200 kg m2. The girl walks to the center of the merry-go-round and stands there. What is the new angular speed of the merry-go-round? (Treat the girl as a point particle.)
