@LK: It looks like you are assuming that the maximum range will occur if he throws the arrows upwards at a 45 degree angle. While this provides the maximum range if H = 0, it does not do so for other values of H. See http://en.wikipedia.org/wiki/Range_of_a_projectile for a derivation of the optimal angle for what they call "uneven ground."
