 P: 63 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 WC=1/2kd^2 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 Help!
 P: 2,258 you are off by a factor of 4 you multiplied by 2 maybe you were supposed to multiply by 1/2
 P: 63 thanks - I tried to recalculate it this is not the case.

According to this equation, you are supposed to multiply kd2 by 1/2, not by 2.
