Explorers on a small airless planet used a spring gun to launch a ball bearing vertically upward from the surface at a launch velocity of 18 m/sec. Because the acceleration of gravity at the planet's surface was g m/sec, the explorers expected the ball bearing to reach a height of s 18t- (1/2)gt m, t sec later. The ball bearing reached its maximum height 20 sec after being launched. What was the value of g? m/sec (Simplify your answer.)
