You wake up one morning to find yourself in a strange room with opaque walls, and no visible doors or windows. You decide to do some experiments to find out more about your strange situation. You drop a ball from a height of 1.55 m above the floor. The ball hits the floor 0.393 s after your drop it. You guess that you must have been taken to an alien planet with gravity different from Earth s. What is this planet s g (that is, the magnitude of the acceleration due to gravity on this planet)?     15.1 m/s^2     34.2 m/s^2     20.1 m/s^2     10.0 m/s^2
