1. The problem statement, all variables and given/known data In order for a volleyball player to jump vertically upward a distance of 0.8 meters, his initial velocity must be? 2. Relevant equations s=v0t + .5at2 vf= v0 + at 3. The attempt at a solution I missed the question the other day on a practice and it has been forever since I messed with this material. Those equations were given as well as the answer, the only problem is I do not know what the letters represent or even how to solve for anything with only information of 0.8 meters. Could someone help me learn this and what the expressions mean so I can solve it?
