**Steve**, Friday, October 5, 2012 at 3:57pmassuming the quadratic equation represents the height of the arrow above the ground at the base of the cliff (and that the shot is made just past the edge of the cliff, so the falling arrow does not hit the cliff), then

the height h as a function of time is

h(t) = 80 + 64t - 16t^2

h=0 when the arrow hits the ground at the base of the cliff.

the rest should be no sweat
