Question 5, 3.4.11 HW Score: 31.11%, 4.67 of > O Points: 0 of 1 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 5.5 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 = 5.5t - (1/2)got m, t sec later. The ball bearing reached its maximum height 10 sec after being launched. What was the value of gs? 04 9s m/sec (Simplify your answer.) 67
