mgh = 1/2 (mv^2)
gh=(v^2)/2
h=v^2/2g
h=100/64.4
h=1.55 ft
if the object goes up over 1.55 feet it is travelingmore than 10 ft/s

i think this is wrong...
first convert feet/sec to meters/sec then do the equations then convert back, you get about 15 feet high if i'm right.
you have to do this because v is squared (if i'm right)
but i'm probably wrong.
