A jet transport with a landing speed of 200 km/h reduces its speed to 60 km/h with a
negative thrust R from its jet thrust reversers in a distance of 425 m along the runway
with a constant deceleration. The total mass of the aircraft is 140 Mg with mass center
at G. Compute the reaction N under the nose wheel B toward the end of the braking
interval and prior to the application of mechanical braking. At the lower speed
aerodynamic forces on the aircraft are small and may be neglected.
