Thank you so much!

It seems I have been fairly misleading as well. Specifically, yes, I want to send something into orbit, and I'm on a budget. All I need to know is how high each stage is going to go, given thrust, mass, burn time, etc. That way, if I can predict the outcome to some sort of degree, I can figure out a rocket that will work the first time around instead of wasting money on rockets that don't make it. Not so much the stages that are used to establish orbit, just the ones that get me up out of the atmosphere. Thank you for other explanations as well.

In response to your question on why I want to calculate it, it's because I'm playing career mode and don't want to waste money on a failed flight that could have been avoided. Thank you for your help though.

As the question states, I need to calculate the altitude a stage of my rocket will be at after it burns, and then how far it will coast. Liftoff stage stats Mass=15.1 t Parts=26 Height=14.8/20m Width=4.3/15m Length=4.3/15m Thrust=315 Isp=230 Burn Time=45.7s Here's a screenshot of the rocket, showing center of thrust and center of mass for the first stage: http://steamcommunity.com/profiles/76561198130134594/screenshot/711904559423379375 (link might be buggy) As you can see, I am using the BACC solid fuel booster for the launch stage. There is this site: http://www.rocketmime.com/rockets/rckt_eqn.html that gives me equations to work with, but I have no idea where to find wind resistance force, among many other things. If someone could give me some equations or formulas(or whatever the term is, I swear I know how to math) along with some explanations that would be very, very appreciated. What I have managed to calculate Area=14.5 TWR=20.9(this was calculated with plugging in 1 for g in the Thrust-To-Weight-Ratio equation, plugging in 9.8^2 instead yields .2, if that is what I was supposed to do) I hope I have provided enough information. Thanks in advance.
