I did not ask to solve a problem. I asked whether my reasoning was correct. And it is a basic physics concepts. The problem is just a mere example. And you have that tag, so you are a little picky, no disrespect.

ok makes sense. What about parts 2 & 3? I think they are correct.

Something like that? I removed numbers and added variables which makes it general:).

comment Does friction act in the same way in different directions?
I see. So, When the textbook goes up the work of non-conservative forces (friction) is ($-20$) joules. Thus, when the object goes down its Potential energy is $180$ joules. When it gets back to the starting point its kinetic energy will be $160$ joules since the friction was ($-20$) joules. I had this idea in mind. I just did not know whether the friction was the same when the textbook was going up and when it was going down. Thanks.

Because she cares the bags for a greater distance. I understand what you say. Should I delete the question or just remove my attempt, so the answers will contain the a complete explanation?

Thanks for timely response. May I edit your answer by adding a graphical representation and short explanations, so others will have a better chance to understand this concept?
