(8%) Problem 9: A basketball player jumps straight up for a ball. To do this, he lowers his body 0.29 m and then accelerates through this distance by forcefully straightening his legs. This player leaves the floor with a vertical velocity sufficient to carry him 0.915 m above the floor. For this problem, use a coordinate system where up is positive.
