the mass of the car 2393 kg, and the coefficient

of the static friction between the road and the

tire 0.9.

Find the magnitude of the normal force N which the road exerts on the car at the opti-

mal speed (the speed at which the frictional

force is zero) of 82 km/h. The acceleration

due to gravity is 9.8 m/s2
