use a free fall equation ... h = -1/2 g t^2 + 233
set h equal to zero and solve for t
... t is the time to fall from 233 m , so double it for the full flight time
A ball is thrown 233 m upward and then falls back to earth.
Neglecting air resistance, how long will it be in the air? The acceleration of gravity is 9.8 m/s2 . Answer in units of s.
