1. Assume an angle, theta.
2. Split the initial velocity into vertical and horizontal components (sine and cosine).
3. Write down the horizontal equation (using the V_x from step 2).
4. Write down the usual vertical equation but h = 0 (bullet starts and ends at same height).
5. Solve horizontal equation for t.
6. Plug t into vertical equation, use some trig identities, and solve for theta.
7. Finally, solve for distance above target (more simple trig).
