16 Three cars of identical mass with identical velocities are driving along the road shown in the figure. Car I is at the bottom of the hill, car II is at the top of the hill and car III is moving horizontally at the instant shown in the figure. II r = 200 m r = 200 m Rank the normal forces on the three cars from largest to smallest. Let n; = normal force on car 1, no = normal force on car II, and nu - normal force on car III, (a) n n nm (b) n > mmm > on (c) n = In > nu (d) n > on > no
