If a person can have a hang time of .75 seconds, how long would it take that individual to go from the ground to the highest point of their jump?

Answer 1

I am wondering what hang time means. It this time of flight?

Answer 2

hang time = time(upwards) +time (downwards),
time(upwards) = time (downwards),
therefore,
time (upwards) = 0.75/2 =0.375 s.
