To return to Earth, the astronaunts aboard Apollo 13 used the moon to slingshot them back to Earth. The spacecraft had a total mass 68,000 kg (including the 1998 kg of fuel and the 3 astronaunts) and was capable of producing 689 kN of thrust. Using this information, determine how long it would take for the Astronaunts traveling at 24,000 mph to perform an emergency burn and return to Earth traveling at 24,000 mph. In other words, how long would it take the Apollo spacecraft to go from 24,000 mph in one direction to 24,000 mph in the other direction. Note: Make time positive.
This question is for a lab class, and we were not given any formula for our lab experiment that I could use to solve this (I don't think)... all I need is a formula, then I can try to solve it...Help would be greatly appreciated. Also, should I assume units are seconds? And convert everything to N, kg, and m/s?
