In our experiment on free-fall, you dropped a "picket fence" through a photogate and the computer recorded the time between the leading edges of the stripes on the
picket fence breaking the beam of the photogate. From this time, you found a graph
of position x versus time t. Suppose this experiment were performed on a different
planet, Planet X, resulting in the graph shown. What is the acceleration due to
gravity on Planet X? (Choose the best answer.)
