Need help with problems 9 and 11 pls 9. Finding g on a small airless planet Explorers on a small airless planetused a spring gun to launch a ball bearing vertically upward fromthe surface at a launch velocity of 15 m/sec. Because the acceler-ation of gravity at the planet's surface was g, m/sec2, the explor-ers expected the ball bearing to reach a height of s = 15t -(1/2)g, 1² meters t sec later.
