Here we go again (yes, this set of questions is starting to feel like Groundhog Day). You AGAIN wake up in a strange room, and this time you drop a ball from a height of 2.10 m, and observe that it hits the floor 0.393 s after you drop it. In this case you suspect you are in deep space, far from any planet or star, and that your rocket is accelerating due to the push of its own engines under the floor. In this case, what must the acceleration of your rocket be?   Question 3 options:   13.6 m/s^2   20.4 m/s^2   46.2 m/s^2   27.2 m/s^2
