A 3% ascending grade meets a 5% descending grade at station 2+110 and elevation 100m. The tangents are connected by an unsymmetrical parabolic curve passing thru a point at station 2+150 having an elevation of 97.078m. If the length of the first curve is 60m, determine: A.) Length of the 2nd Curve = [L2] B.) Stationing of the Highest Point = [StaHP] C.) Elevation of the Highest Point = [ElevHP]
