    Did nobody else notice that they’re pointing the bow lower than 45° but the line is drawn slightly upwards up compensate?

      If you keep falling short, cheat. Or if you keep falling short, your rich parents will prop you up.

    Also if you need your arrows to land all at the same time so you can fool the enemy into thinking you are many archers fire like this.

        Bottom projectile is traveling at a normal speed, just fired last.

          Then the distance must be almost zero, as it exhibits no drop over that range.

            That might have something to do with this being a chart for powered missiles.

                I’m over here with some popcorn as nerds debate the project motion of a hypersonic missile named “arrow” and shit.

    In a frictionless vaccuum 45° would be max range.

        Unless you use modern artillery. Then you want to aim even higher because at those ranges/heights it’s beneficial to reach less dense air layers quickly.

    The optimal launch angle would only be 45 in a vacuum. It’ll be lower if you’re on Earth where there’s air resistance.

      Yeah, that’s why try multiple times and aim higher every time until 45°
      Once you reach that, if you are still falling short, you know you have no chance, unless you increase the launch speed.

      Of course, you can try to properly calculate drag for each projectile and set that as the maximum, but it’s fine for a one-off, assuming you have enough arrows to try again.

    And if you still can’t reach it, ask your god or gods for help,
    as it’s beyond the reach of Mr Newton or even Herr Leibniz.

        Not unless you have something to alter the trajectory in flight.
