Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_64

3/64 The cars of an amusement park ride have a speed \(v_A = 22 \text{ m/s}\) at \(A\) and a speed \(v_B = 12 \text{ m/s}\) at \(B\). If a 75-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.
