A two-engine jet transport has a loaded weight of 94000 Ib and a forward thrust of 8770 Ib per engine during takeoff. If the transport requires 6020 ft of level runway starting from rest to become airborne at a speed of 145 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. Answer R = i Ib

A two-engine jet transport has a loaded weight of 71000 lb and a forward thrust of 9800 lb per engine during takeoff. If the transport requires 4080 ft of level runway starting from rest to become airborne at a speed of 144 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. Answer R = i lb
The 214000-lb space-shuttle orbiter touches down at about 222 mi/hr. At 182 mi/hr its drag parachute deploys. At 40 mi/hr, the chute is jettisoned from the orbiter. If the deceleration in feet per second squared during the time that the chute is deployed is -0.000200v2 (speed v in feet per second), determine the corresponding distance s traveled by the orbiter. Assume no braking from its wheel brakes. Answer: s = i ft
