Prel A ball is thrown straight up from a rooftop 384 feet high. The
formula below describes the ball's height above the ground, h,
in feet, t seconds after it was thrown. The ball misses the
rooftop on its way down and eventually strikes the ground. How
long will it take for the ball to hit the ground? Use this
information to provide tick marks with appropriate numbers
along the horizontal axis in the figure shown.
h= - 16^2+ 80t + 384
The ball hits the ground after
seconds.
