A 93.7 kg basketball player can leap straight up in the air to a height of 83.7 cm, as shown below. The player bends his legs until the upper part of his body is dropped by 58.1 cm, then he begins his jump. With what speed must the player leave the ground to reach a height of 83.7 cm? I'm really stumped on how to do this question. I tried calculating the velocity he has when he reaches the ground, but that isn't right. I don't really know what to do with the distance he drops his body by either. A little help please?
