One way to measure on another planet or moon by remote sensing is to measure how long it takes an object to fall a given distance. A lander vehicle on a distant planet records the fact that it takes 3.17 for a ball to fall freely 11.26 , starting from rest. What is the acceleration due to gravity on that planet? Express your answer in .
