You need to design an industrial turntable that is 55.0 centimeter in diameter and has a kinetic energy of 0.245 Joule when turning at 45.5 rpm (rev/min).
(a) Find what must be the moment of inertia of the turntable about the rotation axis?
kg • m2
(b) If your workshop makes this turntable in the shape of a uniform solid disk, determine what must be its mass?
kg
