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 fvs. fx for this motion is shown below.

The last data point corresponds to the maximum displacement of the mass.
Determine displacement from equilibrium position (x = 0) at a time of 2s.
