Hello! I was able to determine where majority of the diagrams with great confidence, however, three of them left me puzzled. I made my best educated guesses for the three circled in green.
-Please, note that the 1st circled diagram has wheels, therefore it does not have friction forces. It also does not have a rope, therefore there is no tension. Additionally, it is seemingly at rest (v=0).
-Please, note that the second circled diagram is not touching the carpet, therefore, friction forces are not acting upon it. Also, there is a rope, therefore tension is involved.
-Please, note that the third circled diagram has wheels, therefore it does not have friction forces. It also does not have a rope, therefore there is no tension. It seems to not to match any of the force diagrams/equations.
Could you help me determine where the three diagrams, circled in green, belong? Thank you so much!
