A person throws a ball upward while standing on top of a barn that is 18 feet high. The ball has an initial velocity of 64 ft/s. The motion of the ball is modeled by the equation h=18+64t-16t^2 , where h is the height of the ball (in feet) after t seconds. a.) At what time foes the ball reach its maximum height? Solve by rewriting the equation into vertex form.
b.) What is the maximum height? Use your work from part a to help you find the maximum height.
c.) At what time does the ball hit the ground?
