A A wooden plank is placed on top of two identical, solid, parallel cylindrical rollers, as shown in the figure below. The plank has a mass of M= 5.40 kg, and the rollers each have a mass of m= 2.00 kg and a radius of R = 6.00 cm. The plank is pulled by a constant horizontal force F of magnitude 7.20 N applied to the end of the plank and perpendicular to the axes of the cylindrical rollers. The cylinders roll without slipping on a flat surface, and there is also no slipping between the cylinders and the plank. At the instant shown in the figure, the rollers are equidistant from the ends of the plank. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) What is the magnitude (in m/s2) and direction of acceleration of the plank at the instant shown? m/s² magnitude direction --Select--- (b) What is the magnitude (in m/s2) and direction of acceleration of the centers of mass of the rollers at this…
