Both of them act in the clockwise direction, I think. The linear acceleration of the plank should be two times that of an individual roller.

Woops, I have fp and fg mixed up, so it should be fg - fp because friction with the ground acts in the direction of the applied force. Then a is the linear acceleration of one of the rollers. Since there is no slipping between the cylinders and the plank, linear acceleration should be equal to...

Homework Statement A plank with a mass M = 6.10 kg rides on top of two identical, solid, cylindrical rollers that have R = 4.10 cm and m = 2.00 kg. The plank is pulled by a constant horizontal force F of magnitude 4.80 N applied to the end of the plank and perpendicular to the axes of the...
