Hi,
If I have a plank (mass M) resting on two identical parallel cylinders (mass m, radius R) and I pull the plank with a horizontal force F (no slipping between cylinders and floor nor between plank and cylinders), what happens? How can I find the acceleration of the plank and the rolling cylinders? Why DOESN'T a = F/M give the acceleration of the plank AND the tangential acceleration of the cylinders?
Thank you!
