anyone know any formulas to guide or track a rocket or to predict where one would land?

There is some stuff there that should be useful, there are many rocketry sites, do a bit of searching...

Predicting a flight path is very hard. the cloest way other then just geussing is by useing some math and drawing up a parabolic flight path. but to do that ul need to know the final velocity (when it runs out of fuel) resistance, wind, gravity and all sorts of other crap. So really if u plan to really try and predict its path useing maths ull need to know alot about ur rocket. I studyed parabolic paths a few months ago.
