An archer shoots an arrow into the sky where the motion of the arrow can be modeled by the equation f(t) = –16t^2 + 80t where t is time in seconds and f(t) is height in feet. Find how long it will take the
arrow to hit the ground using an algebraic method. Show all of your reasoning/steps used with this algebraic
method
