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.
