The correct answer was 5.48x 10' seconds. This was obtained by equating the gravitational force to the centripetal forceand transposing to get T = V(4π2R3/GM).Errors included incorrectly copying the formula or incorrectly transposing the equation. There was also confusion overwhich mass or rad...
The ISS travels at about 17,500 miles/28,000 kilometers per hour. At this speed, the ISS orbits the Earth every 90 minutes, which gives the crew 16 sunrises and sunsets every day. Since humans have been living and working on the space station, it has orbited Earth tens of thousands o...
