The gravitational force on a 1.4 kg object = m g = 1.4 x 9.807 = 13.73 Newtons.
-- If a force of 2.5 N acts against gravity, then the net downward force on
the object is 11.23 N.
-- 11.23 N = 81.79% of the object's weight, so its acceleration is 81.79% of the
gravitational acceleration = 8.02 meters per second2
