2 A VERTICAL PARBOLIC CURVE WAS DESIGN IN ORDER TO HA CLEAR SIGHT DISTANCE OF 120 M. THE GRADE LINES INTERSECT AT STA 9+000 AT ELEV 1160.50. THE CURVE WAS DESIGN SUCH THAT WHEN THE HEIGHT OF THE DRIVERS EYE IS 1.50 M ABOVE THE PA YMENT IT WOULD JUST SEE AN OBJECT WHOSE HEIGHT IS 0.10 M ABOVE THE PAVEMENT. DETERMINE THE MAX SPEED THATA CAR COULD TRAVEL GRADE OF 5% AND A DOWNGRADE OF -3%.
