Make the following assumptions:
-- Ignore air resistance ===> all objects fall at the same rate, i.e. same distance in the same time.
-- It drops from a stand-still ... nobody throws it down.
x = 1/2 G t2
t = sqrt( 2x / G ) = sqrt(140/32.2) = sqrt(4.348) = 2.085 seconds (rounded)

How long would it take a water balloon to drop 200 feet?
if you ignore air resistance, it would take about 3.5 seconds; at ttat point where it hits the ground it is traveling at 75 mph. Because of the air drag, it may take a bit longer to hit the ground.
