A. A light plain is coming in for a landing at a speed of 100 km/hr. The wheels have zero rotation just before touching the runway. If 1/10 the weight of the plane is maintained by the upward force of the runway for the first second, what is the approximate length of the skid mark left by the wheel on the runway? The wheels each weigh 100 N and have a radius of gyration of 180mm and a diameter of 450 mm. The plane weighs with load 8,000 N. The coefficient of friction between the tire and runway is .3.
