A basketball rolls without slipping down an incline of angle ?. The coefficient of static friction is ?s. Model the ball as a thin spherical shell. (Use any variable or symbol stated above along with the following as necessary: m for the mass of the ball and g.) (a) Find the acceleration of the center of mass of the ball. (b) Find the frictional force acting on the ball. (c) Find the maximum angle of the incline for which the ball will roll without slipping.
