hello! what a way to ask me qn lol! anw, for the friction thingy, it depends on which side the system is moving? if let's say mass A is greater than mass B and the mass A will pull the pulley down in its direction, then the friction will be the force in the opposing motion of the direction of motion. i think?
and for math, i dunno how to help you like that, if u really need to ask then call me ba lol but i'm sure u will manage during tutorial la x) i dunno how to do qn 5 though haha
