An unsymmetrical parabolic curve has a forward tangent of 10% and a back tangent of +6%. the length of the curve on the left side (P.C) is 60m. If the vertex is at elevation of 100 m and the rate of change in grade of the first curve is -2% per 20m length, determine the following: A. Elevation of P.C. B. Elevation of P.T. C. Length of the Second Curve
