Two solid cylinders are rotating about an axis that passes through the center of both ends of each cylinder. cylinder a has half the mass and twice the radius of cylinder b, but they have the same rotational kinetic energy. what is the ratio of the angular velocities, ns/on, for these two cylinders? take the moment of inertia for a solid cylinder as mr? , with mass m and radius r.- a) 0.28 b) 0.71 c) 0.50 d) 1.0 e) 4.0
