The 300-Mg jet airliner has three engines, each of which produces a nearly constant thrust of 240 kN dur- ing the takeoff roll. Determine the lengths of runway required if the takeoff speed is 220 km/h. Compute s first for an uphill takeoff direction from A to B and sec- ond for a downhill takeoff from B to A on the slightly inclined runway. Neglect air and rolling resistance.
