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 25.5 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 = 25.5t – (1/2)g,tť m, t sec later. The bll bearing reached its maximum height 30 sec after being launched. What was the value of g.? 9e = m/sec“ (Simplify your answer.)
