The hieght of the arrow t seconds after it was shot into the air is given by s(t)=-16t^2 +96t. When should the arrow reach its greatest hieght.Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!s(t)=-16t^2 +96t At the vertex, when t = -b/2a t = -96/-32 = 3 seconds (time at max height) t = 3 --------- s(3) = -16*9 + 96*3 s(3) = 144 feet max
