Hello, I have just started playing KSP. I have looked through the games Wikipedia but I am unable to find the information to calculate what I need to know. Any help appreciated: What is the formula for calculating the speed and altitude a rocket will achieve within an atmosphere? Basically I want to know how high up a very basic rocket will go and how fast it will travel. I have learned a lot about the theory in this game in the last few hours but I am a bit rusty using formula so please keep things basic. Thank you for your help.
