A ball is thrown upward from the top of a building 240 feet tall. The height of the ball is described by the function h(t) = -16t? + 18t +240, where t is in seconds and t = 0 corresponds to the moment the ball is thrown. a) Determine for what value of t the ball reaches the maximum height and determine this maximum height. t= and maximum height = b) Determine when the ball reaches the ground.
