i was reading a golf simulator forum. i am actually interested in writing a code and make graphs to see how trajectory path looks like. For any given time (t) the distance traveled (x component) is x(t) = (Vo cosm)t and the height (y component) at any given time (t) is y(t) = (Vo sinm)) - (gtÂ²)/2 I mentioned the equation above but i can't figure out what is A with cap sign in this equation. Please i desperately need an answer on that. hope some one can take away my curosity on this. as i have to start working on it and make code ready ASAP. any help would be appreciated.
