1. The problem statement, all variables and given/known data From a stationary standing position, a basketball player leaps straight up, reaching a height og 1.0 m above the ground. How long is the player in the air? 2. Relevant equations I think I could use y=y0t+v0t+1/2at^2 3. The attempt at a solution I've found the formula that looks best to use for this problem. I know a=9.8 m/s^2. I know, letting up be positive, that y=1.0 m and yinital=0 m. The equation I want to use wants me to know the inital velocity. How do I find it? I don't think it is zero, because he's leaping up. I could use v^2=v0^2=2aΔx, but I don't know the final velocity, either. Thanks in advance for clarification!
