Explorers On A Small Airless Planet Used A Spring Gun To Launch A Ball Bearing Vertically Upward From The Surface At A L 1 (28.15 KiB) Viewed 45 times
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 8.5 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=8.5t−(1/2)gs​t2 m,tsec later. The ball bearing reached its maximum height 10sec after being launched. What was the value of 9s​ ? gs​=m/sec2 (Simplify your answer.)
