Metal sphere oscillates at the end of a vertical spring

Reference no: EM13565037

A 0.20-kg metal sphere oscillates at the end of a vertical spring. As the spring stretches from 0.13 to 0.21 m (relative to it sunstrained length), the speed of the sphere decreases from 5.3 to4.6 m/s. What is the spring constant of the spring?
