Best Answer: Time of flight t = 2vy/g Distance = vx*t = 2vx*vy/g We must maximize vx*vy as a function of launch velocity v. vx = vcosÎ¸, vy=vsinÎ¸ Thus we must maximize sinÎ¸cosÎ¸. At the maximum, the derivative of sinÎ¸cosÎ¸ = 0. From the ref, the derivative = cos(2Î¸).Thus cos(2Î¸) = 0, 2Î¸ = 90 deg, Î¸ = 45 deg.'d put optimal at a lower angle, say 20 to 30 degrees, to keep most of the air time while reducing the energy lost at landing and improving the horizontal speed component for the post-landing roll.
