A vehicle is traveling in the outside lane of a non-superelevated curve of radius 4200 feet, with an adverse crown of 2%. If the velocity is 50 mph, what side friction factor (expressed in decimal form X.XX) is required to keep it on the curve?

EXTRA CREDIT!!! Two tangents of a spiraled horizontal curve meet at a deflection angle, I = 41°00’00”. The radius of the circular curve portion is 1300 feet and the length of spiral is 325 feet. The X and Y coordinates of the SC point for a spiral curve have been computed as 324.49’ and 13.53’, respectively. What is the chord distance from the TS to the SC (to the nearest hundredth of a foot)? (integer response required)
