(5%) Problem 20: A basketball player jumps straight up for a ball. To do this, he lowers his body 0.32 m and then accelerates him through this distance by forcefully straightening his legs. This player leaves the floor with a vertical velocity sufficient to carry 0.895 m above the floor. For this problem, use coordinate system where up is positive. 33% Part (a) Calculate his velocity when he leaves the floor in m/s.
