And ping pong balls falling from 40 feet will reach terminal velocity? Again my point is to link Sir Isaac Newton's claim to the experiment that the OP is wishing to reconstruct. Why must you change the context to try and show different results for a different experiment?I don't know what the terminal speed of a ping pong ball is or how close it would get to that in 40 feet, but I expect that the speed will be high enough for the effects of drag to be significant.
EDited to add: Google tells me:
The Terminal Velocity is about 9.5 m/s
98% of which is attained after falling 12.5 m
I'm NOT changing the context. The effects I'm describing, which I believe will manifest in this experiment as described, and which you say do not exist, are precisely what the OP is trying to demonstrate. The experiment is NOT trying to prove Sir Isaac's claim. If anything, it is disproving it.
Then I guess we will both be interested in reading what the final results and findings of the OP's experiment are.
