Question
Nikola Jokic is running at 8.5 m/s directly toward the basket when he jumps into the air to dunk the ball. He is only able to maintain a constant horizontal jumping velocity of 85% of his running velocity during the entire flight phase of the jump. (a) What does his vertical takeoff velocity in m/s have to be when he first leaves the ground so that his center of mass is able to achieve a maximal vertical displacement of 0.7 meters during the jump? (b) How far from the basket (measured in the horizontal direction) in meters must he start his jump so that he reaches his maximum vertical jump displacement at the same time that he reaches the basket?
