1. The problem statement, all variables and given/known data Hello, I need to solve a problem which involves a projectile being fired at a target that is at a different height. Given a firing angle, the distance the projectile needs to needs to travel and gravity, i need to compute the flight time and initial velocity needed to reach the target. I don't have and specific problem with specific numbers to work with but I can just toss out an example. A projectile is being fired at 45 degrees, at a target 2000 meters away and 500 meters off of the ground. 2. Relevant equations 3. The attempt at a solution The difference in height is completely throwing me off.
