Problem 1: A pan of negligible mass is attached to two identical springs of stiffness k = 250 N/m.If a 10-kg box is dropped from a height of 0.5 m

above the pan, determine the maximum vertical displacement d. Initially each spring has a tension of 50 N. Note: May need numerical methods or trial-and-error for final step.
