# Rotational Dynamics:Motion of wheels of an stopping airplane

An airliner lands with a speed of 100 m/s. Each wheel of the plane has a radius of 1.5 m and a moment of inertia of 120 kg?m2. At touchdown the wheels begin to spin under the action of friction. Each wheel supports a weight of 1.50 x 10^4 N, and the wheels attain the angular speed of rolling without slipping in 0.5 s. What is the coefficient of kinetic friction between the wheels and the runway? Assume that the speed of the plane is constant.
