I'm working on a problem that gives me the initial velocity and angle at which the ball is thrown and that it happens on the moon, but that's it. So I only have 2 knowns in the x and y direction. I'm supposed to find how far and how high the ball is thrown before striking the ground. Am I able to set the final velocities equal to zero so I can have 3 of 5 variables? The examples I've looked at haven't done that so I'm confused. Is it possible to solve this?
