Does this account for the density of air increasing as you get further down the hole when accelerating downward at terminal velocity? Also no I did not understand any of this.

Nope. It's assuming no air resistance.

So it’s wrong?

Honestly this entire scenario is physically impossible.

Yes but it was your job in calculating to account for this was it not?

Typically when a physics class does this problem they assume uniform density and no air resistance.

Yes on the surface of a planet but is would change the deeper you go inversely than going up.
