Acceleration due to gravity question?

  1. Sep 29, 2008 #1
    If I know the acceleration of gravity (9.81m/s^2), and I'm given an initial velocity in the positive x direction, how would I go about figuring how far will an object fall in a given time?

    I think this a 2-dimension projectile, but I don't see how to solve. If y=yo+vot-1/2gt^2, then y=-1/2gt^2. Any help is greatly appreciated!

    The velocity in the x direction won't affect the velocity in the y direction. All you need is that first equation.
