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.
