I don't want the answer, I just wanna know if there are any sites with a tutorial on how to do this sort of problem. (I have a whole sheet of these and last time I asked a question for help on my HW I got yelled at).

An astronaut and a satellite are in an environment where no net external forces act on them. The astronaut tugs on the satellite with a force of 9.5 N in positive x-direction. What is the x-component of the force exerted by the satellite on the astronaut?

I can only find out how to do problems on incline planes, friction, etc... in my book.

never mind i found out. If anyone was wondering it is -9.5 N

I'm in Physics as well, if I'm not mistaken, isn't this a Net external force problem? :D

Yes, it is.

Falling under motion in a plane.

And no math was involved in the problem solving either :)
