1. A ball is thrown upward from the top of a 12 meter high building at a speed of 25 meter per second. The ball's height above ground can be modeled by the quadratic equation, H(t) = -17t² + 25t + 12 a) What is the maximum height reached by the ball ? b) How long does it take for the ball to reach the ground? c) What is the height of the ball, 1.5 seconds after it is thrown from the building?
