If a ball is thrown vertically upward from the roof of 32 foot building with a velocity of 80 ft/sec, its height after t seconds is s(t) = 32 + 80t – 16t². What is the maximum height theball reaches? 132What is the velocity of the ball when it hits the ground (height 0)? 90What is the acceleration of the ball when it hits the ground (height 0)? -32

Here I am attaching image so that you understand each and every step.
