Web4 Sep 2012 · Now we'd say that a velocity to the northwest is the sum of a positive north-south velocity and a negative east-west one. If we were talking about an airplane instead of a car, we'd need to introduce a third dimension, with positive velocity corresponding to climbing and negative velocity to descending. Web11 Nov 2024 · Use the Tsiolkovsky rocket equation: Δ v = v e l n m 0 m f where Δ v is how much your velocity changes, v e is the effective exhaust velocity, m 0 is the initial mass of rocket plus fuel, and m f is the final mass of the empty rocket. I started with 63% = ( e − 1 e) because then m 0 m f is e, whose natural log is 1, meaning Δ v = v e.
