B A A block (B; mass=5 kg) rests on a pallet (A; mass=3 kg). The coefficients of friction between the pallet and the floor are 0.3 and 0.4, while the coefficients of friction between the block and the pallet are 0.6 and 0.8. A rope is attached to the block, horizontally applying an unknown force FA a) Draw a free body diagram for the block, and another for the pallet. Carefully label all forces, and where applicable, draw lines to connect the Newton's third law pairs (or identify them by using subscripts).

(Hint: what will happen if the rope is pulled too hard?) 2 X m/s2
