A grade ascending at the rate of 6% meets another grade descending at the rate of 4% at the vertex of elevation 21.00 m and stationing 9+685.78. The height of the eyes of the drivers above the pavement at each end of the sight distance which is 165 m long is 1.5 m. (a) Determine the length of the vertical parabolic curve in m. (b) Compute the stationing of the highest point of the curve. (c) Compute the elevation of the highest point of the curve in m.
