WebbThese two values of terminal velocity are the velocities that the landing raptors will need to cancel out. Assuming no gravity loss (the burn time is very short so this is an okay assumption for this type of rough analysis) over the landing burn period the raptors will need to supply 100 m/s of delta-V on Earth and 480 m/s of delta-V on Mars to land safely . Webb10 mars 2024 · Once you know both the final and initial velocity, you can calculate the average velocity of an accelerating object. To do this, add initial velocity to final velocity and divide the result by 2. In this case, 6m/s + 30m/s divided by 2 = 18 m/s north. The method for finding the velocity of an object around a circle is a little different.
