The equation h = -16t^2 + 112t gives the height of an arrow, shot upward from the ground with an initial velocity of 112 ft/s, where t is the time after the arrow leaves the ground. Find the time it takes for the arrow toreach a height of 180 ft.

put in for h 180 ft, factor (you may have to use the quadratic equation), and solve for t.

We will be happy to critique your thinking, or work.
