Question 1119803: An astronaut on the moon throws a baseball upward. The astronaut is 6ft, 6 in tall, and the initial velocity of the ball is 40 ft per second. The height s of the ball in feet is given by the equation s=-2.7t squared+40t+6.5, where t is the number of seconds after the ball was thrown. After how many seconds is the ball 22ft above the moons surface?
