The cars of an amusement park ride have a speed vA = 18 m/s at A and a speed vg = 11 m/s at B. If a 56-kg rider sits on a spring scale which registers the normal force exerted on it), determine the scale readings as the car passes points A and B. Assume that the person's arms and legs do not support appreciable force.

The cars of an amusement park ride have a speed vA = 18 m/s at A and a speed vg = 11 m/s at B. If a 56-kg rider sits on a spring scale
(which registers the normal force exerted on it), determine the scale readings as the car passes points A and B. Assume that the
person's arms and legs do not support appreciable force.
