Social ScienceAs you are riding in a 1650-kg car, you approach aN7M.8hairpin curve in the road whose radius is 50 m. The road-bed is banked inward at an angle of 10°(a) Suppose the road is very icy, so that the coefficient ofstatic friction is essentially zero. What is the maximumspeed at which you can go around the curve?(b) Now suppose the road is dry and that the static frictioncoefficient between the tires and the asphalt road is 0.6.What is the maximum speed at which you can safelygo around the curve?
