018 (part 1 of 2) 10.0 points A civil engineer is asked to design a curved section of roadway that meets the following conditions: With ice on the roadj when the coefcient of static friction between the road and rubber is 0.21, a car at rest must not slide into the ditch and a car traveling less than 80 km/ h must not skid to the outside of the curve. The acceleration of gravity is 9.81 m/s2 . At what angle should the road be banked? Answer in units of 0. Answer in units of D. 019 (part 2 of 2) 10.0 points What is the minimum radius of curvature of the curve? Answer in units of m. Answer in units of m
