Question: A constant horizontal force F is applied to a lawn roller in the form of a uniform solid cylinder of radius R and mass M

A constant horizontal force F is applied to a lawn roller in the form of a uniform solid cylinder of radius R and mass M (Fig. P10.78). If the roller rolls without slipping on the horizontal surface, show that
(a) The acceleration of the center of mass is 2F/3M and
(b) The minimum coefficient of friction necessary to prevent slipping is F/3Mg. (Hint: Take the torque with respect to the center of mass.)
