Question 1022423: a baseball player player hits a pitched a ball when it is 4 ft above the ground. The initial upward velocity is 80 ft/s. How long will it take for the ball to hit the ground

is the height at whatever time is
is due to downward pull of gravity
is upward velocity
is initial height
------------------------
You want to find when , because that
is the ground level
Use quadratic formula
( note that I used the negative square root so
that I would end up with positive time )
sec
The ball hits ground in 5.05 sec
Here's the plot:
Hope I got it!
