Michael Jordan won the 1987 NBA Slam Dunk Contest. While doing a slam dunk in the local motion capture lab, an average vertical ground reaction force of 2900 N (Normal Force) acted on Jordan's take off foot for 0.21s during the upward phase of his slam dunk jump. a) What would his take-off velocity off the ground be if his mass was 95 kg b) If Jordan's center of gravity (COG) was 1.3 meters above the ground when his foot came off the ground, what is the maximum height his CoG reaches during the jump.
