Kinematics equation?

  1. Oct 13, 2008 #1
    Hi there, I'm new here, but is there an equation that shows you the position of an object as a function of initial speed (or velocity) and launch angle? I need help finding such a way to get this, but I have no idea where to start. Thanks a lot!

    you can set a coordinate system here,
    if we set x the horizontal derection,and y the derection of the gravity.
    then x=v0 x cos(angle) x t
    and y=v0 x sin(angle) x t -1/2gt(square)
    of cause you can unit them.
