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

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
