Represent and reason $A2\mathrm{.}0-kg$ cart attached to a spring undergoes simple harmonic motion so that its displacement$-$versus$-$time is described by $x=(0\mathrm{.}20m)cos(\frac{2}{2\mathrm{.}0(s)}t).$ Construct qualitative work$-$energy bar charts for the cart$-$spring system at the times indicated in the table that follows.
