Folding Platform

Folding Platform#

A platform of length \(x = {{params.x}}\ \rm{m}\) is being folded up against a wall by a rope pulling on its end. The rope is retracting at a constant rate of \(\dot{\ell} = {{params.l_dot}}\ \rm{m/s}\). The distance between the pivot and where the rope is pulling from is \(h = {{params.h}}\ \rm{m}\).
