Problem:
A mass of 0.5 kg oscillates on the end of a spring on a horizontal surface with negligible friction according to the equation. The graph of F vs. x for this motion is shown below.
The last data point corresponds to the maximum displacement of the mass.
Determine angular frequency ω of the oscillation?
