A Formula-1 car encounters a hump which has a circular shape with smooth transitions at both ends. (a) What speed VB will cause the car to lose contact with the road at the topmost point B? (b) For a speed vA = 190 km / h, what is the normal force exerted by the road on the 640-kg car as it passes point A?
