Calculate a person’s hang time if he moves horizontally 3 m during a 1.25-m high jump. What is his hang time?

what determines hang time is vertical motion, since the only force acting is gravity.

if your max height is 1.25m, then your time to fall is given by

height = 1/2 gt^2 or t=sqrt[2h/g] = sqrt[2*1.25m/9.8m/s] = 0.5s

this is the time to descend, so the total hang time is 1s
