An ideal spring hangs from the ceiling. A 2.15 kg mass is hung from the spring, stretching the spring a distance d = 0.0905 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L = 0.0225 m from the equilibrium position and released. What is the kinetic energy of the mass at the instant it passes back through the equilibrium position?
