Question 606570: Liz drops a marble from the top of a cliff 96 feet off the ground. The height
of the marble is described by the quadratic equation h = -16 t square + 96
where h is the height in feet and t is the time in seconds. Find the time t
when the marble hits the ground. Round to the nearest hundredth.

You can put this solution on YOUR website! Liz drops a marble from the top of a cliff 96 feet off the ground. The height
of the marble is described by the quadratic equation h = -16 t square + 96
where h is the height in feet and t is the time in seconds. Find the time t
when the marble hits the ground. Round to the nearest hundredth.
.
When the marble hits the ground, the height (h) is zero. So, set h to zero and solve for t:
dividing both sides by -16: seconds
