Homework Help: Work done on a spring

  1. Mar 7, 2016 #1
    1. The problem statement, all variables and given/known data

    I reference the problem posted here: https://www.physicsforums.com/threads/work-and-spring-problem.194531/

    2. Relevant equations

    Work = Force * Distance

    F = kx

    3. The attempt at a solution

    Wouldn't the limits of integration in part 2 be from 5 to 9, since x is the compression distance, not the length of the spring?

    Thanks!
