Re: Win a Hat! (Its a really nice hat, its a really hard problem)
It's not a single equation. It's 2 equations... you will need the equation in 2 directions... x and y
x = x(original position) + v(original velocity in x direction)t
y = y(original position) +v(original velocity in y direction)t + 1/2 g(t squared)
Your original velocity in the x and y come from your angle (theta)
Use trig... solve for relationship between these two and then you can get the angle you need.
I am a physics teacher... I am not giving you the final equations... use trig and algebra .... you can do this....
