A 65 kg person is standing 0.5 meters from the center of a merry-go-round that is spinning with angular frequency w = radians/second. When no one is on it, the merry-go-round has moment of inertia of 150 kg m2. The person walks toward the edge and stands 1.5 meters from the center of the merry-go-round. (a) What is the angular velocity of the merry-go-round when the person is 1.5 meters from the center? (b) Compare the final rotational kinetic energy of the system, KEF, to the initial rotational kinetic energy of the system, KEI (i.e. did the system lose or gain kinetic energy?) 1.7
