The Panavia Tornado with a mass of 18.000 kg lands at a speed of 213 km/h. The decelerating force (in newtons) exerted on it by its thrust reversers and aerodynamic drag is 80,000 + 2.5v2, where v is the airplane’s velocity in m/s. What is the length of the airplane’s landing roll? (See Example 14.4.)
