In the vertical jump, an athlete starts from a crouch and jumps upward as high as possible. Even the best athletes speed little more than 1.00 s in the air (their "hang time"). Treat the athlete as a particle and let their ymax be their maximum height above the floor. To explain why they seem to hang in the air, calculate the ratio of the time they are above ymax/2 to the time it takes them to go from the floor to that height. Ignore air resistance.
