Need Source of Projectile in Vacuum Outcome

  1. May 15, 2008 #1
    https://www.physicsforums.com/showthread.php?t=75116 (the url has spaces) it said "shooting the projectile at 45 degrees will yield the greatest distance..." Where do you find that information. I need to know for my scientific experiment for school. I know this fact is true, but where is the source of this information? Thnx in advance.

    Sorry if I post this is the wrong section. I really don't know where this thread should go o_O

    One can derive a set of kinematic equation (for constant acceleration) using Newton's second law. The equations of most interest are,

    [tex]s = v_0t+\frac{1}{2}at^2[/tex]

    And the defintion of speed,

    [tex]v = \frac{d}{t} \Rightarrow t = \frac{d}{v}[/tex]

    One then needs to consider motion in the vertical and horizontal directions separately. For more information you can try Googling for Projectile Motion.
