I was able to answer it using my original answer. I had to find the ratio of H/R, which is sinθ/4cosθ or (1/4)tanθ. I set (1/4)tanθ=H/R and solved for θ, which gave me θ=arctan(4H/R), which is the correct answer.

I found the position function in the x direction and set it equal to R/2. This gave me that the time, t, such that the position of x is R/2 is t=v0sin(2θ)/2gcosθ. I can use trig identities to simplify this to t=v0sinθ/g I can find the position function of y: Sy=v0t-4.9t2, but I'm not sure...
