An airliner

An airliner lands with a speed of 54.5 m/s. Each wheel of the plane has a radius of 1.25 m and a moment of inertia of 110 kg · m2. At touchdown, the wheels begin to spin under the action of friction. Each wheel supports a weight of 1.40 â 104 N, and the wheels attain their angular speed in 0.522 s and start rolling without slipping. What is the coefficient of friction between the wheels and the runway? Assume that the speed of the plane is constant.
