SHM, Determing Spring Constant from Period^2 vs. Mass

  1. May 4, 2008 #1

    I'm trying to find the spring constant (k) of a spring using simple harmonic motion. I have a graph of Period^2 vs. Mass.

    Knowing that T=2*[tex]\pi[/tex]*[tex]\sqrt{m/k}[/tex]

    How would one find k from the slope of this graph?
    My linear fit yields: y=5.237x+0.003
    5.237 being my slope

    HINT: Using what you know can you get an Equations for T^2 in terms of mass? If so, the slope of that equation is 5.237.
