Hi All,

The majority of people who have stated that the two spheres will arrive
at the "same time" are mistaken. The 10-kg sphere will definitely
arrive first, if only by milliseconds. Now if you had dropped the spheres
on the Moon, the majority answer would be correct. But wind resistance
on earth after 100 meters of freefall cannot be discounted, and the
ballistic coefficient of the denser object is going to come into play.

But, the question was defined, stating spheres of specific weight, in a
classic physics example. No masses of varying energies or quarkiness,
just
good old simple fun to see who would fall for the "what falls faster, a
pound of feathers, or a pound of lead?"

Mark, lost in a land where most would have said the 10 (whats a kg?)
would.
