Problem: An ideal spring of negligible mass is 13.00 cm long when nothing is attached to it. When you hang a 3.15-kg weight from it, you measure its length to be 14.40 cm .If you wanted to store 10.0 J of potential energy in this spring, what would be its total length? Assume that it continues to obey Hookes law.
