Hello
Let's convert first the height from foot to meters:
This is the space covered by the ball in its accelerated motion, where the acceleration is the gravitational acceleration:
The law of motion is given by
Re-arranging, we can get the total time of the motion:
which is the time the ball takes to hit the ground.
