Energy & Spring Displacement function

  1. Nov 17, 2014 #1
    1. The problem statement, all variables and given/known data
    What would be the energy required to stretch a spring of [tex]\vec{F}spring = - (ax+βx^2)\hat{x}[/tex] where[tex]\vec{x} = x*\hat{x} [/tex]

    2. Relevant equations

    [tex]\vec{A}/|A| = \hat{A}[/tex]
    [tex]|\vec{A}| = sqrt(A*A)[/tex]
    [tex]A = (A^x)^2 + (A^y)^2[/tex]


    3. The attempt at a solution

    So far I'm at a loss just getting started.

    Hello White, welcome to PF :)

    To get started:
    Do you know the energy required to stretch a spring of ##\vec F = -a\vec x ## ? How was that expression derived ?
