Force constant

  1. Nov 1, 2012 #1
    1. The problem statement, all variables and given/known data

    Two 3.5 g masses are attached by a spring has a vibrational frequency of 7.00 s-1. Calculate
    (a) the force constant of the spring; (b) the zero point energy; (c) the potential energy if the
    maximum displacement is 0.5 cm.


    2. Relevant equations
    k=((2πcω)^2)μ
    E=(1/2)hcw

    (NOTE: The omega(w) in the formulas has a ~ over the top representing wave number which has the units 1/cm)

    3. The attempt at a solution

    The question gave me the vibrational frequency of 7.00/s. I don't how to put the frequency in terms of 1/cm so i can plug it into the force constant formula

    These don't look like the right equations for the problem. They're from optics, not mechanics. Do you not have an equation for the SHM of a mass on a spring?
