ball is thrown from the top of a building and falls to the ground below. Its path can be modelled by the relation H = -4t^2 + 8t + 32, where H is the height above the ground in metres, and t is the time in seconds. a) What is the approximate height of the building? b) How long does it take the ball to hit the ground?
