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
The Attempt at a Solution
Ι have found the speed of the board but i don't know how to find the acceleration.
