The car (650 kg) starts from point A with a speed of 3 m/s, as shown in Figure
Q2(b). Determine the minimum height, hA, required for the car to complete the
loops without losing contact with the track. Neglecting friction, determine the
normal force acting on the car at points B and C, respectively.
