Resources Hint An ideal spring hangs from the ceiling. A 1.95 kg mass is hùng from the spring, stretching the spring a distance d = 0.0845 m from its original length when it reaches equilibrium. The mass is then lifted up a distance L = 0.0265 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? kinetic energy J Equilibrium position WWW.c wwwW.
