Ajet transport with a landing speed of 300 km/hr reduces its speed to 65 km/hr with a negative thrust r from its jet thrust reversers in a distance of 440 m along the runway with 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.
