1. The problem statement, all variables and given/known data What is the maximum vertical height to which a baseball player can throw a ball if his maximum throwing range is 54 m? vertical: a=9.8 m/s/s, Vyo=0 m/s, d=?, t=? horizontal: d=54 m, a=0 m/s/s, Vxo=?, t=? 2. Relevant equations d=Vo*t+.5*a*t^2 3. The attempt at a solution Since Vo or theta was not given, I decided to graph a parabola who's derivative would be 9.8t...so on my calculator I graphed 4.9t^2. Since I know it traveled 54 meters horizontally, I thought the y value of the parabola when x=27 would be my answer..but it clearly was not. Any ideas on how to approach this? I'm confused because of the few givens I have to work with.
