That depends upon the force needed to pull the first block, before the second block was added.
It also depends upon whether the two blocks are still being pulled at constant speed.
Presumably the force is needed to overcome friction. If the same kind of wood is in contact in the second block, the required force increases by a factor 6/2.5 = 2.4
