Homework Help: Simple but tricky problem, horizontal motion

  1. Oct 4, 2006 #1
    Im studying for my test and I have a problem from my previous notes. It should be simple but I am having some difficulty.

    A cannon is shooting horizontally at a target. The cannonball strikes .2m below the bullseye. If the initial speed of the cannonball is 956m/s, what is the distance?

    Any help would be appreciated.

    Draw a picture of what it looks like, include the path if there was no gravity and then draw the actual path. You are solving for D_y that should be plenty to get you started.

    Find the value of t from the vertical displacement. Then find horizontal distance by using the value.
