Question

a massless spring is placed vertically on the ground. a ball of mass m is then placed on top of the spring, and the spring is compressed a distance L from equilibrium by pressing down on the top of the ball witha pushing forc Fp.

Before the spring is released, the ball is a height d above the ground. When the spring is released, the ball reaches a maximum height of h above the surface of the ground

If the pushing force Fp is 2 times the weight of the ball, use conservation of energy to derive an equation for the compression distance, L, in terms of only d and h
