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 dv=1/2at^2 t=vv/a dh=vht 3. The attempt at a solution dv=1/2at^2 8=1/2(9.8)t^2 √ans t=1.63sec 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).
