3. There is a vertical curve. The grade into the curve -3.6% and the grade out of the curve +4.4%. If the design speed is 60 mph, calculate the minimum required length for the vertical curve based on stopping sight distance (Hint: Find the stopping sight distance for the design speed of 60 mph first and then use formula in the textbook to calculate minimum length for the vertical curve).
