Homework Help: Frequency question.

  1. Sep 22, 2013 #1
    1. The problem statement, all variables and given/known data
    A mass of 0.3kg is suspended from a spring 200Nm. If the mass is displaced by 10mm from its equilibrium position and released, for the resulting vibration, calculate:

    a. the frequency of vibration.

    2. Relevant equations
    ω = √ k/m
    f = ω/2∏

    3. The attempt at a solution
    ω=√ 200/0.3 = 25.82 rads-1

    so f = ω / 2∏

    f = 25.82/2∏ = 4.11Hz

    Does this seem to be correct? Any help would be appreciated.
