(10) [7 points] For a solid spherical ball of mass M

(10) [7 points] For a solid spherical ball of mass M and radius R to roll M without slipping down an incline with angle 6 to the horizontal, some a friction is needed. (a) Draw a free body diagram illustrating the forces and torques acting L on such a spherical ball. (b) Find an expression1 for the friction force needed. (c) Find the static coefficient of friction. Answers to (b) and (c) should depend on nothing other than M, R, 6, and g. (d) What fraction of the total kinetic energy is in translational motion
