A cockroach (mass m = 0.015 kg) ison the lazy Susan, at a distance of 10 cmfrom the center. Both the cockroach and the lazy Susan areinitially at rest. The cockroach then walks along a circular pathconcentric with the axis of the lazy Susan at a constant distanceof 10 cm from the axis of the shaft.
