I did it again and still got 25.7. Either way, at least I know I'm doing it right. Thanks a lot for the help.

Okay, so here's what I did. Assuming the following: vertical acceleration = -9.81 m/s^2 initial vertical velocity = V0sin45 m/s vertical displacement = -1.5 m horizontal acceleration = 0 m/s^2 initial horizontal velocity = V0cos45 m/s horizontal displacement = 68.75 m Okay, so using...

So the vertical displacement would be only -1.5m? But that doesn't account for when it went up in the air and came back down does it?

I don't know how to solve for the time for it to fall back to earth. If I only have two variables then I'm not sure how to do it. In order to solve for time I would also need to know either the final velocity or the vertical displacement, and I have neither of those. The vertical...
