in fig;11-60, a constant f horizontal force epp of magnitude 12 app n is applied to a uniform solid cylin der by fishing line wrapped around the cylinder. the mass of the cylinder is 10 kg, its radius is 0.10 m, and the cylinder rolls smoothly on the hori zontal surface. (a) what is the mag nitude of the acceleration of the center of mass of the cylinder? (b) what is the magnitude of the angular acceleration of the cylinder about the center of mass? (c) in unit-vector notation, what is the frictional force acting on the cylinder?
