1. The problem statement, all variables and given/known data A basketball player achieves a hang time of 0.843 s in dunking the ball. What vertical height will he attain? The acceleration of gravity is 9.8 m/s2. Answer in units of m. 2. Relevant equations I'm not sure what to use, but I think [itex]\Delta[/itex]x = vit + 1/2 at2 could work. 3. The attempt at a solution I divided the hang time (0.843s) by two before plugging it in because I just wanted to find the vertical height, but I'm not sure if that's what I should do. I guess initial velocity would be 0? I arrived at -2.1m. The absolute value of this is incorrect as well. Solving this way using the given time (not halved) does not yield the correct answer either. I think the problem is initial velocity. What should it be? I'm really not sure how to do this one. The wording is vague and I feel like there's not enough information. Any help would be really appreciated, thank you guys.
