In some movies where we see people in space, they sometimes show “gravity” being generated by rotating a cylindrical object at some rotational velocity. (a) let’s say that this “space wheel” has a diameter of 165 m and a rotational period of 19 seconds. based on this, what is the apparent gravity for someone walking on the walls? [5 points] (b) what is causing this artificial gravity? further, we see this being effective for generating gravity in movies, but it is not useful in real life. why not?to put michael bay and ridley scott in their respective places!
