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 to reach a height of 180ft.
Do I plug 180 in for h?
180=-16t^2 +112t
0= -16t^2 +112t - 180
Then....quadratic equation?
