Asked by Kasey
Nicole throws a ball straight up. Chad watches the ball from a window 5.0m above the point where Nicole released it. The ball passes Chad on the way up, and it has a speed of 10m/s as it passes him on the way back down. How fast did Nicole throw the ball?

V^2 = Vo^2 + 2g*d
Vo^2 = V^2 - 2g*d
Vo^2 = 10^2 - (-19.6)98*5
Vo^2 = 100 + 98 = 198
Vo = 14.1 m/s. = Speed at which ball was thrown.
