It would take the ball 1.5 seconds to reach it's apex highest point) and an equal 1.5 secons to fall to it's starting height.
Velocity = Acceleration X Time
V= 32.2 ft/sec2 x 1.5 seconds
V= 48 ft/sec. This is the vertical "muzzle velocity" of the throw and the vertical velocity of the ball when caught. Horizonatl velocity is inconsequential. I'm sure you all agree that a bullet fired from a "level" barrel 6 feet off the ground will hit the ground exactly at the same time as another bullet dropped from that same height.
Velocity = Sqaure Roof of 2g x H
48x48 = 64.4 x H
H= 36 feet!
Most gyms having ceilings 25 feet high as they are of masonry construction and limited in height by the National Concrete Masonry Code. This story is getting very dubious......

Nice analysis!
