A two-engine jet transport has a loaded weight of 72000 lb and a forward thrust of 9710 lb per engine during takeoff. If the transport requires 3950 ft of level runway starting from rest to become airborne at a speed of 138 knots (1 knot = 1.151 mi/hr), determine the average resistance R to motion over the runway length due to drag (air resistance) and mechanical retardation by the landing gear. R = _______lb
