The 90,000-kg jet airliner is being stopped by brake action only. The engines are at idle and producing negligible thrust, and the velocity of the aircraft is too slow to produce measurable aerodynamic lift or drag. Only the main landing gear is equipped with brakes, and the coefficient of friction between the tires and runway is 0.8. If under these conditions the brakes are applied hard enough that the main wheels are on the verge of slipping, determine the vertical force on the nose wheel strut.

[The distance between the nose and the main landing gear is 20 m]
