You need to find where is
the height above ground, and is the time in seconds
for the ball to hit the ground. The equation is:
In words:
( height above ground ) = ( effect of gravity pulling down ) + ( starting height above ground )
Note that at when the ball hasn't started dropping yet
ft ,as it should be
----------------------------
When the ball hits the ground, the height is zero, so
and
sec
It takes the ball 2.25 sec to hit the ground
