In the vertical jump, an athlete starts from a crouch and jumps upward to reach as high as possible. Even the best athletes spend little more than 1.00 s in the air (their "hang time"). Treat the athlete as a particle and let Ymax be his maximum height above the floor. v Part A v To explain why he seems to hang in the air, calculate the ratio of the time he is above ymax/Z (moving up from ymax/2 t0 Ymax and then moving down t0 Ymax / 2) to the time it takes him to go from the floor to that height. Ignore air resistance. 4.82 Previous Answers Correct
