Oscillations Lab! HELP ME PLEASE

  1. Nov 9, 2009 #1
    1. The problem statement, all variables and given/known data

    Please calculate the units for the spring constant k in two fashions. First, from
    Hooke’s Law (eqn. 5 in lab manual), and then from the period equation for a spring
    (eqn. 3). Please show that these units are compatible (i.e. mean the same thing).

    2. Relevant equations
    equation 5 k=Mg/x
    equation 3 T=2[tex]\pi[/tex][tex]\sqrt{}M/k[/tex]

    3. The attempt at a solution

    well i am pretty sure that Hooke's law give N/m but i have no idea how to show that the units for the second equation are compatible with the first...any ideas on how to figure this out?

    Just plug in the units for M and T and isolate the units of k.
