1. The problem statement, all variables and given/known data An Olympic long jumper is capable of jumping 8.5 m. How high does he goes? (Assuming he lands standing upright). His initial horizontal velocity is 9.7 m/s. Before it asked his height, I found that the time he is in the air is 0.88 seconds. 2. Relevant equations Y=Yinitial+Vyinitial*t-.5at^2 3. The attempt at a solution Since Y is the maximum height, I just tried plugging in numbers for the symbols in the rest of the equation. Yintial was 0, Vyintial was 0, t was 0.44 because max height is in the middle, and a is -9.80m/s2. I got an answer of 9.5, which was wrong. I have a feeling I'm substituting incorrectly but can't figure out what.
