A small cart of mass \(M\) moves at a constant speed \(v_0\) along a continuous track containing four distinct sections. Point \(W\) is at the bottom of a circular dip of radius \(2R\), point \(X\) is at the bottom of a circular dip of radius \(R\), point \(Y\) is at the top of a circular crest of radius \(2R\), and point \(Z\) is on a flat horizontal segment. The speed of the cart satisfies \(v_0^2 < 2gR\) so that the cart never loses contact with the track. Which of the following correctly ranks the magnitude of the normal force \(F_N\) exerted by the track on the cart at the four points?
