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 12 m/sec. because the acceleration of gravity at the planet's surface was gs m/sec2, the explorers expected the ball bearing to reach a height of s=12−(1/2)gst2 m, t sec later. the ball bearing reached its maximum height 20 sec after being launched. what was the value of gs?
