Homework Help: Simple projectile motion, yet stuck.

  1. Oct 30, 2012 #1
    1. The problem statement, all variables and given/known data
    A student threw a ball horizontally out a window 8.0m above the ground. It was caught by another student 10.0m away. What was the initial velocity of the ball?
    ANSWER PROVIDED: 7.16m/s

    2. Relevant equations

    3. The attempt at a solution

    The fact that I'm trying to find it's initial velocity causes my brain to become a blank slate when deciding on what my next step should be (if the first is even right).

    is the other student supposed to be at ground level or something? What's the height which the ball is caught?
