A. 0 B. 1 C. 2 D. 3 ?
A baseball is thrown upwards from a height of 5 feet with an initial speed of 64 feet per second, and its height h (in feet) from the ground is given by h(t) = 5 + 64t – 16t^2 as shown in the graph where t is time in seconds. Using a graphing calculator, at what time does the ball reach its maximum height?
