1. The problem statement, all variables and given/known data http://postimage.org/image/7rgmo1527/ How is the speed decreasing and acceleration decreasing in this problem? 2. Relevant equations Kepler's Laws? 3. The attempt at a solution I remember in lecture my professor was saying something along the lines of objects attracting each other. So, since there are two stars that are maybe attracting each other, as they get farther and farther apart by a distance of r, shouldn't the speed increase--because the force of attraction (already negligible) is even smaller as they go farther apart? Does this question pertain to Newton's laws or Kepler's laws? Thank you for your time!
