resistance propotionell to the square of the velecito

I think you're saying there was a medieval theory of
projectiles that predicted this shape for trajectories,
prior to the invention of cannons.

Yes I meant medieval, but I didn't know how to spell it.
I have seen picture in a book where the projectile
Move in a stright line and the it falls right down.

I do belive that projectile's always have followed parabola's.
But I think it's fun that when the velecito is
Very high, the orbit looks like the picture in a book.
