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 height s of the ball in feet is given by the equation s=−2.7t2+50t+6.5, where t is the number of seconds after the ball was thrown. Complete parts a and b.

0 is its x and y coordinate
