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 50 ft per sec. The heights of the ball in feet is given by the equation s= -2.71² +50t+6.5, where t is the number of seconds after the ball was thrown. Complete parts a and b. a. After how many seconds is the ball 18 ft above the moon's surface? After seconds the ball will be 18 ft above the moon's surface. (Round to the nearest hundredth as needed. Use a comma to separate answers as needed.) ents Libran
