A jet transport with a landing speed of 300 km/h reduces its speed to 100 km/h with a negative thrust R from its jet thrust reversers in a distance of 600 m along the runway with constant deceleration. The total mass of the aircraft is 170 tons with mass at center. Compute the reaction under the nose wheel 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.
