Metal sphere oscillates at the end of a vertical spring

Reference no: EM13660878

A 0.66-kg metal sphere oscillates at the end of a vertical spring. As the spring stretches from 0.14 to 0.25 m (relative to its unstrained length) the speed of the sphere decreases from 6.15 to 4.55 m/s. What is the spring constant of the spring?
