urprisingly, very few athletes can jump more than 2.2 ft (0.66 m) straight up. Use d = 1/2 gt2 and solve for the time one spends moving upward in a 2.2 foot vertical jump. Then double it for the "hang-time" -- the time one's feet are off the ground.

    ho=0
    hf=.66m

    hf=ho+1/2 9.8 t^2 solve for t, then double it.
