An airplane lands with a speed of 150km/h. Before landing the airplane's wheels are not rotating. The ground exerts a constant normal force of 12,000N on each wheel. The coefficient of kinetic friction between the runway and a tire is 0.60. A wheel has a moment of inertia of 2.9 kg m^2 and a radius of 0.15m. How long is the skid mark that the tire leaves on the runway?
