Aroadway is built with the following conditions: with ice on the road, when the coefficient of static friction between the road and rubber is 0.09, a car at rest must not slide into the ditch and a car traveling less than 50 km/h must not skid to the outside of the curve. the acceleration of gravity is 9.81 m/s.
what is the minimum radius of curvature of the curve?
