Let the radius oh a circular segment be 110 m, the mass of the car 1508 kg, and the coefficient of the static friction between the road and tire 0.9. Find the magnitude of the normal force N which the road evers on the car at the optional speed (the spurred at which the frictional force is zero) of 85 km/h. Answer in units of N
