I suspect what he is getting at will be clearer to you if you reverse what he is saying and see if you think that is correct: i.e. if you don't believe the speed of a falling body is independent of its weight, do you feel it is dependent on its weight?"
I already posted the formula a couple times.
If you don't believe me, then how about NASA?
