Please describe step by step for the each part

Consider a gymnast of mass m = 51.4 kg that jumps on a springboard with a spring constant k = 8.70 * 10^3 N/m, compressing the board a distance of d = 0.557 m, that then launches her straight upward. Find the maximum height that she launched to by: a) Finding the energy stored in the spring when the gymnast fully compresses the springboard. (8 points) b) Find the speed at which the gymnast leaves the springboard. (Hint: it is where the springboard returns to equilibrium) (8 points) c) Find the top height h that the gymnast is launched. (9 points) (Hint: think carefully about where and how you define zero potential energy from gravity and the spring) A h
