To explain why he seems to hang in the air, calculate the ratio of the time he is above Ymax /2 (moving up from ymax /2 to ymax and then moving down to ymax /2) to the time it takes him to go from the floor to that height. Ignore air resistance.

Question
Review ConstantS 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. Part A To explain why he seems to hang in the air, calculate the ratio of the time he is above ymax/2 (moving up from ymax /2 to ymax and then moving down to ymax/2) to the time it takes him to go from the floor to that height. Ignore air resistance. ΑΣφ. ?
