An ideal spring of negligible mass is 13.00cm long when nothing is attached to it. When you hang a 3.30-kg weight from it, you measure its length to be 14.50cm .
If you wanted to store 10.0J of potential energy in this spring, what would be its total length? Assume that it continues to obey Hooke's law.
