Because of your knowledge of physics and interest in the environment, you have gotten a summer job with an organisation which wants to orbit a satellite to monitor the amount of chlorine ions in the upper atmosphere over Australia. It has been determined that the satellite should collect samples at a height of 100 km above the Earth's surface. Unfortunately, at that height air resistance would make the amount of time the satellite would stay in orbit too short to be useful. ...
