1. The problem statement, all variables and given/known data The problem is in the attached image 2. Relevant equations 3. The attempt at a solution I understand that the diagram of A is displaying negative acceleration and the diagram of B is displaying positive acceleration. However, I am struggling to find an answer for the question. I'm also wondering if the diagram of B can be flipped around and still represent the same thing. I am admittedly not the best physics student and any help is appreciated. Thank you.
