Question 2

An astronaut is piloting a spacecraft, which is in a circular orbit around Earth. A space station is ahead, on the same circular orbit. If he fires his rockets briefly to increase the forward speed of the rocket, what will happen?
 
  What will be an ideal response?

Answer to Question 1

E

Answer to Question 2

The spacecraft will be put into an elliptical orbit with a perigee, the distance of closest approach to the center of Earth, equal to the original radius. The average radius of this orbit is larger, so it will take longer to complete one revolution. So when he completes one revolution, bringing him back to the original radius, he will have fallen further behind.
