I have a simple problem that i can't seem to get right.
An ideal spring has a spring constant k = 22.0 N/m. What is the amount of work that must be done to stretch the spring 0.70 m from its relaxed length?
I tried W = (-)1/2 k x^2
= - (.5)(22.0) (.7^2)
= -5.39
but this isn't correct any suggestions.
Thanks
