Work to Compress Spring
1. The problem statement, all variables and given/known data
A spring, with a spring constant of 87 N/m, was compressed a distance of 8.6cm (0.086m). How much work was done in order to compress the spring?
2. Relevant equations
3. The attempt at a solution
I tried to plug in the numbers as follows in the above equation - but I can't get the answer out. I have been doing this for ages am like a broken record - pse snap me out of this programming!
WC= 2*87*.086^2 = 1.286904J
Apparently, the correct answer is .32J

you are off by a factor of 4
you multiplied by 2
maybe you were supposed to multiply by 1/2

thanks - I tried to recalculate it this is not the case.
