Homework Help: Spring Potential

  1. Apr 24, 2012 #1
    If I have a spring connected to a roof with a natural length of l, then the spring potential at any point can be given as

    0.5k(x-l)^2.

    Assuming the datum is at the roof.

    If the datum is at the natural length of the spring then the equation is

    0.5kx^2+c

    The trouble I have is to dertmine c. Could anyone give some tips on that?

    Thanks.
