Concept Simulation 2.3 offers a useful review of the concepts
central to this problem. 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 +18.7 m/s and measures a time
of 14.2 s before the rock returns to his hand. What is the
acceleration (magnitude and direction) due to gravity on this
planet? (positive = up, negative = down)
