“You are a consultant for a new Star Trek movie. You were hired to make sure that any science in the movie is correct (We will not discuss tachyon bursts and sub space and/or temporal anomalies!). In the script , the crew of the Enterprise (NCC 1701 E, repaired after the encounter with Shinzon of Remus in Nemesis) discovers an abandoned space station in deep space far from any stars. This station, which was built by Earth in the 21 st century, is a large wheel-like structure where people live and work in the rim. In order to create “artificial gravity”, the space station rotates on it’s axis. Captain Picard asks chief engineer Geordi La’Forge to figure out at what rate (angular speed) a space station 195 meters in diameter would have to rotate to create “gravity” equal to 0.7 that of Earth.”
Notice the only information I actually need to solve the problem is in just the very last sentence. I think my physics professor is kind of a geek.
