Bow and Arrow
This is a photo that I took a few weeks ago of my brother shooting a bow and arrow in our backyard. Mind you, he made that bow himself by taking a branch off a tree and carving it. He may not go to private school, but talented kind nonetheless. The arrow being shot off obviously has force from the bow being applied to it. We can assume that xN are pushing it towards wherever it is heading and the only resistance it is facing is from the air and wind (would this be considered friction?). The arrow being shot is also not in free fall, though if it were, it would be falling at a rate of 9.8m/s^2.

my kind of brother. cool!
i remember making tiny bows with twigs and then using those shish-ka-bob sticks as arrows when i was a kid.
yes, wind, et. al. is air resistance, so arrows are not technically in free fall. Plus, the flights (feathers/stuff at the end help stabilize the arrow in flight so that also disqualifies arrows from being in "free fall"
