You are designing a curve in a highway. If the turn is too sharp (the radius of curvature is too small), then cars may lose traction. Find the minimum radius of curvature of a road so that a 1000kg car doesn't skid. The speed limit is 15m/s and the static friction between the tires and the road is 2000N.
