... Finalize Note that the acceleration component ax is independent of the mass of the car! It depends only on the angle of inclination and on g. From Equation (2), we conclude that the component of Fg perpendicular to the incline is balanced by the normal force; that is, n = mg cos θ. This situation is ...
