The ball in Exercise 47 will never reach a height of 100 ft. How can this be determined algebraically?

Exercise 47

An astronaut on the moon throws a baseball upward. The astronaut is 6 ft, 6 in. tall, and the initial velocity of the ball is 30 ft per sec. The height s of the ball in feet is given by the equation s = -2.7t² + 30t + 6.5, where t is the number of seconds after the ball was thrown.
