Problem 2: The 300 metric tonne jet airliner has four engines, each of which produces a nearly constant thrust of 180 kN during the takeoff roll. Determine the length s of runway required if the takeoff speed is 220 km/hr. Compute s first for an uphill takeoff direction from A to B and second for a downhill takeoff from B to A on the slightly inclined runway. Neglect air and rolling resistance. Ans. (a) S-807 m (b) s#751 m
