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

You have been hired as a physics professor by some aliens and taken far far away to their ‘planet’. Being curious, you wanted to find out which ‘planet’ you were on. With an alien stopwatch you determined the time for a 2.0 kg alien object released from a height of 2.5 m to hit the ground to be 1.75 s. 1. What is the acceleration due to gravity on the alien ‘planet’? 2. With what speed does the alien 2.0 kg object hit the ground?
