Hey guys, I'm having some trouble finding the exact quantity of energy storied in this spring problem.
It's like a problem with parts A and B, part A says "Determine the amount of work required to stretch the spring from 0 to 20 cm. I found that to be 125J. For Part B, it says "Suppose that this spring was stretched 7.753 cm. Find the exact quantity of energy stored in the spring.
I think that the equation that i would use is the one for elastic energy, Ee= 1/2kx^2
The Attempt at a Solution
So far i have Ee= 1/2kx^2
I'm not sure if i'm doing this right, or what to do next.
