Solved: An ideal spring of negligible mass is 12.00 cm
Chapter 7, Problem 7.14(choose chapter or problem)
An ideal spring of negligible mass is 12.00 cm long when nothing is attached to it. When you hang a 3.15-kg weight from it, you measure its length to be 13.40 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
