I think the answer JDG needs is that the masses of the hammer and the feather are totally irrelevant. IT is the mass of the earth that dominates when you drop anything. The force of gravity is an acceleration, a constant which is applied equally to all objects until you get to large masses like the moon, then the mass of the moon becomes significant.
