I did a quick'n'dirty numerical simulation with a 0.1-sec ∆t, assuming vertical launch instead of 75°. For altitude the 75° elevation angle will make a little difference (the computed altitude will be a bit high) but it won't make a lot of difference, since sin(75°) is getting pretty close to 1. (But see the caveats below!) The 0.1-sec ∆t will make some ...

Towards the lower end Your rocket is slamming into a wall of air. Altitude has a quadratic response to reduction in velocity. Part 1: Getting up to speed with the calculations you have probably already performed. For instance, it would be nice to know what speed the rocket is moving at when the engine burns out. While gravity and drag also acts upon the ...
