How much wood could a woodchuck chuck if a woodchuck could chuck wood?

The answer to this depends on various factors.  If the wood if very heavy, a woodchuck may not be capable of chucking it at all.  If the pieces are smaller and the woodchuck was relatively young and spritely, then they could probably chuck at least 30 to 40lbs within a few hours.  An older woodchuck may no longer have dexterity in its hands or the sufficient strength needed to chuck any piece of wood regardless of its size or weight.
