The figure shows an overhead view of a merry-go-round type ring structure, with its axis of rotation at the center of the two circles. The inner radius is Ry, which is 0.33 times R2 (R2 = 0.74 m). The mass M of the structure is 8.0 kg (ignore the mass of the crossbars and axle at the center). The ring structure initially rotates at w = 7.42 rad/s. At first, a robotic car of mass m = 0.25 times M is located at the outer rim (at R=R2) of the rotating structure. By how much does the car increase the kinetic energy of the car-ring system if the car moves to the inner edge at R=Ry? Assume the car can be treated as a point mass. AK = R1 R2
