if m2 weighed 2 kg and m1 weight 6 kg, which direction does the static friction point for m2? Does it point up and to the left or down and to the right. I said down and to the right because without friction, the pulley would pull it up, so since static friction points in the direction the object would move if there were no friction, then it would be down and to the right. I am so confused. someone help. I can figure the whole problem i have here but i just don't know which direction the static friction points which messes up my freebody diagram, which in turn messes up the signs in the equations, which in turn messes up the answer. Please help!
