An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of + 15.5 m/s and measures a time of 13.9 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet?
