You wake up in a strange room and you drop a ball from a height of 1.02 m above the floor. The ball hits the floor 0.319 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earths. What is this planets g (that is, the magnitude of the acceleration due to gravity on this planet)?     36.0 m/s^2     20.0 m/s^2     10.0 m/s^2     15.0 m/s^2
