I'm having some difficulty doing this lab, so if anyone could point me in the right direction that would be awesome.(adsbygoogle = window.adsbygoogle || []).push({});

I basically have to determine what angle to set a launcher at so that the projectile will hit a falling target. I have to derive an actual equation. The only measurements I will be able to make is the height of the target (before it falls) and the distance from the launcher to the target.

I've uploaded a crummy diagram of the set-up:

Remember, the only variable I'll be able to insert values for is 'h' and 'Dx'. I know that I have to start with the five kinematics equations, but I've reached a dead end.

Has anyone done this lab before? Is anyone able to point me in the right direction?
