1. The problem statement, all variables and given/known data Plank of mass M = 8 kgr is installed on the same two tubes (very small thickness) radius R and mass m = 2 kgr. Initially the system property. A horizontal force F = 40 N applied to the board and the tubes rolled without sliding (Ic = mR^2). When the board shifted s = 2m on the ground calculate: a. the speed of the board b. the acceleration of the board c. the friction between board and the tubes d. the friction between tubes and floor 3. The attempt at a solution Ι have found the speed of the board but i don't know how to find the acceleration.
