I want to make sense of this, so explanations are highly appreciated.

arwym · Answer

I would especially like to understand how to determine the kinetic friction given the static friction.

badhi · Answer

you can start by marking the forces acting upon each of the object :)

anonymous · Answer

Arwym u said B has largest mass, if it has, A will not go down. the question is wrong
