A highway has a flat section with a tight curve of radius 40 m. The curve is level with respect to the ground. If the coefficient of static friction between tires and pavement surface is 0.45, what is the maximum speed v at which a car of inertia m can negotiate the curve safely —that is without the tires slipping?
