If Micheal Bolton and Kenny G are thrown out of an airplane at the same time, who hits the ground first?

Although you've failed to figure in wind resistance. I can't remember which, but I think it's Kenny G who has the "Mass 'o' Hair (tm)" That might act as a wind baffle just enough to marginally slow his acceleration. So while they'll both reach terminal velocity and make a satifying splotch on the ground... Michael Bolton will get there fractionally sooner. Assuming my memory of who has the hair is correct.

no, that's what I meant about the density...they're so close to the same density, they'd have to be falling a lot farther than a plane can go to make it make a difference.
And they both have the Massive Hair gene.

wind resisitance is a function of surface area vs mass. In other words: density. That's what controls terminal velocity: The point when wind resistance balances gravity and you stop accerating.

There was a time and a place where I would have actually tried to figure out their respective masses and drag coefficients and tried to math this out. But... well that's about 15 years in my past. In HS we were on a band trip to Toronto and a bunch of us had just taken Physics so we attempted to figure out whether a human falling of the CN Tower observation deck would reach terminal velocity before going splat. Yes we were geeks.

For reference yes... you would reach terminal velocity about 100 feet off the ground
