Aliyah is solving a physics problem involving an elevator. She draws the (unlabeled) force diagram for the elevator show on the right and says "this force diagram could represent an elevator moving upwards." José disagrees. Looking at the force diagram he says "the way you've drawn the force diagram the elevator CANNOT be moving upwards. It MUST be moving downwards because the force pointing down is bigger than the force pointing up." (a) Correctly label the force diagram. (b) Who do you agree with and why? For the statement you disagree with, how would you convince him/her that he/she is incorrect?
