4) A ball of mass m is pressed against a spring mounted platform a distance d. The ball is then released, it reaches a height h above the natural length of spring-mounted platform before it falls back down toward the platform. Assume that the spring is perfectly ideal with spring constant k, and that the masses of the spring & platform are negligible, and there is no air resistance. (a) Using g to represent the acceleration due to gravity, find an expression for mass of the ball in terms of g, h, d, and k. (b) As the ball falls back toward the platform, determine an expression for ball's speed when it strikes the platform.
