    Geala,

    Those energy numbers you gave are at the point of launch. As soon as a projectile leaves its launcher (bow, sling, gun barrel) it begins to slow down. Irregular shaped/non-aerodynamic objects will slow faster. There are online ballistics calculators to show how much energy a projectile has at different ranges and trajectory as well. I believe you would need to know the BC (ballistic coefficient) of the projectile though...

    Also, are the weights you are giving in grams (g) or grains (gr)?
