A plank of mass M = 3.4 kg, moves on two identical solid cylinders, whose moments of inertia, with respect to the center of mass, are given by I = (1/2) mR^2, where m = 2.8 kg is the mass of each cylinder and R is its radius. The plank is pulled with a constant horizontal force F = 11.3 N. Assume that the cylinders roll without sliding, both with the plank and with the floor. What is the force of friction between the rigid body and the plank
