Let the radius of the circular segment be 92 m,
the mass of the car 2393 kg, and the coefficient
of the static friction between the road and the
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
