A free-floating ball is attached to three springs that are anchored to posts at points (0,0), (0, 1), and (2, 0) on the plane, each with the same spring constant k = 2kg/s. The ball will eventually come to rest at the point that will minimize the total (elastic potential) energy of the system. Find the coordinates of this point where the ball comes to rest. %3D
