A 70 kg merry-go-round disk has a radius of 3 meters and spins at 1.4 radians/sec with the 80 kg person on the edge. If the person moves so that they are now only 1 meter from the center, calculate the new angular speed of the merry-go-round system. Calculate the total kinetic energy of the system when the person is at the edge and when the person is at the 1 meter spot.
