A science class designed a ball launcher and tested it by shooting a tennis ball straight up from the top of a 15-story building. They determined that the motion of the ball could be described by the function: ℎ() = −162 + 144 + 160, where represents the time the ball is in the air in seconds and ℎ() represents the height, in feet, of the ball above the ground at time . What is the maximum height of the ball? At what time will the ball hit the ground?
