Let's say the launch speed is constant, but you can adjust the launch angle, and again we will deal with the special case where the landing point is at the same vertical level as the launch point. In this case, which launch angle will produce the maximum range? 45 degrees, angle less than 45 degrees, angle greater than 45 degrees, or does it depend?
