Homework Help: Find Amplitude and Equilibrium in Simple Harmonic Motion

  1. Apr 24, 2013 #1
    1. The problem statement, all variables and given/known data

    A 0.241-kg particle undergoes simple harmonic motion along the horizontal x-axis between the points x1 = -0.349 m and x2 = 0.419 m. The period of oscillation is 0.511 s. Find the frequency, f, the equilibrium position, xeq, the amplitude, A.

    2. Relevant equations

    The hint system suggests:

    Midpoint Formula: (X_1 + X_2)/2
    Distance Between Two Points: |X_1 - X_2|

    3. The attempt at a solution

    I am just not sure how I get amplitude and equilibrium from this information. The hint system suggests that I draw the setup to determine these however I am lost from there.

    I would suggest you consider the definitions and equations of frequency, equilibrium and amplitude. After drawing the system, consider how these quantities are represented in the system.
