Simple compression problem

  1. May 8, 2010 #1
    Hi there,

    For this question, I've been asked to calculate the maximum energy a spring can store when compressed by 8cm. I've already found the spring constant to be [tex]5.0\times 10^5\ Nm^{-1}[/tex] (which is correct), so I thought it was just a simple matter of pluggung the values into the formula: [tex]E_e=\frac{1}{2}kx^2[/tex]

    When I do this I get the answer: [tex]2.0\times10^5\ J[/tex], but the book says the answer is [tex]1.6\times10^3\ J[/tex]

    Thanks for your help
