An astronaut on the moon throws a baseball upward. The astronaut is 6'6" tall and the initial velocity of the ball is 30 ft./s. The height s of the ball In feet is given by the equation s=-2.7t^2 + 30t + 6.5 where t is The number of seconds after the ball is thrown. After how many seconds is the ball 18 feet above the moon surface
