A block with a mass of 0.300 kg attached to one end of a spring can oscillate on a frictionless, horizontal surface. Initially the block is displaced 0.120 m from its equilibrium position and then it is released. After 0.152 s the block has not passed through the equilibrium position and is located 0.0371 m from its equilibrium position. Determine the spring constant of the spring.

A horizontal spring is attached to a wall at one end and a mass at the other. The mass rests on a frictionless surface. You pull the mass, stretching the spring beyond the equilibrium position a distance A, and release it from rest. The mass then begins to oscillate in simple harmonic motion with amplitude A. During one period, the mass spends part of the time in regions where the magnitude of its displacement from equilibrium is greater than (0.17)A—...
