I am trying to predict how long a rocket will take to predict its trajectory, given target location, general rocket information, starting position, etc. I am currently in high school and working on my science fair project. I have people who would be willing to explain higher level math/physics to me, so feel free to use advanced math and physics in your answer.

Please don't double-post questions. See a response to your question here: https://www.askmehelpdesk.com/physics/time-trajectory-721700.html
