A ball is thrown into the air with an upward velocity of 28 ft/s. Its height (h) in feet after t seconds is given by the function h = –16t² + 28t + 7. How long does it take the ball to reach its maximum height? What is the ball’s maximum height? Round to the nearest hundredth, if necessary

Question

anonymous · Answer

when the ball reaches maximum height it speed is zero .... or |dw:1332186422782:dw| the slope is equal to zero
