In the figure, a constant horizontal force F app of magnitude 77.6 N is applied to a uniform solid cylinder by fishing line wrapped around the cylinder. The mass of the cylinder is 16.3 kg, its radius is 0.815 m, and the cylinder rolls smoothly on the horizontal surface. (a) What is the magnitude 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? Fapp Fishing line (a) Number Units (b) Number Units (c) Number i + i Units
