a 220g mass is on a friction less horizontal surface at the end of a spring that has force constant of 7.0 N/m. the mass is displaced 5.2 cm from its equilibrium position and than released to undergo simple harmonic motion. At what displacement from the equilibrium position is the potential energy equal to the kinetic energy.
