hello all. Im a bit stuck on a math problem. I am trying to figure out what the parametric equations of a trajectory with a gravitational force pulling west and south. My first questions are should the t variable be squared and the gravity multiplied by .5 in: x=(v(o)cos(angle))t-.5gt2 I think this because its counterpart, y, has this. would it also go something like: distance=x= [((v(0)^2)sin(2*angle)]/ [g(w)*g(s)] where g(w) represents gravity pulling west, and g(s) for gravity south. What i question in this is is g(w) is multiplied by g(s). i think this is correct but i would really appreciate a confirmation from a math wiz (the people on this site). Thanks!!
