Imagine you are observing a 18800 kg helicopter from atop a
mountain. You see it as two-dimensional motion and can assume its
movement in the xy-plane. The sum of all the forces acting on it from
your point of view can be described by the potential energy function
U(x, y) = (0.380 J/m²)x² − (0.140 J/m²)y².
