hi I was wondering in what circumstances would we use the friction coefficient?

Before B hits the floor, A is being pulled down by both its own weight plus tension. After B hits the floor, A is only pulled down by its own body weight and thus must slow down. How have you calculated acceleration to be higher instead of lower after B hits the ground?

Would the diagram be included in the exam or would we have to sketch something like this?

how do you know what directions the tensions go in for each object/block?
