A merry-go-round rotates at the rate of 0.20 rev/s with an 80kg. man standing at a point 2.0 m from the axis of rotation.

a) What is the new angular speed when the man walks to a point1.0 m from the center? Assume that the merry-go-round is asolid 25 kg. cylinder of radius 2.0 m.

b) Calculate the change in kinetic energy due to the man's movement. How do you account for this change in kinetic energy?
