Question: Nicole throws a ball straight up. Chad watches the ball from a window 5.80m above the point where Nicole released it. The ball passes Chad on the way up, and it has a speed of 13.0m/s as it passes him on the way back down.
Question 1: How fast did Nicole throw the ball?
I need help to determine the how fast did Nicole throw the ball.
