A plane lands with a speed of 51.0m/s. Each wheel of the plane has a radius of 1.25 meter and a moment of inertia of 110kg•m2. At touch down the wheels begin to spin under the action of friction. Each wheel supports a weight of 1.40 104 Newton, and the wheels attain their angular speed in 0.52 second while rolling without slipping. Find the coefficient of kinetic friction between runway and wheels? Suppose that the speed of the plane is constant.
