In case someone wants to know, I spoke to my teacher. I got partial credit for the exercise. She made emphasis in the fact that the position r(t) was like a single vector, and that the set of all position vectors gives you the trajectory, which can be obtained from y(x). I told her that I...
In my opinion, the question was a generic theoric question, hinting without saying that I should find an y(x). But the thing is that answers in which some people marked x(t) and y(t) as the answer were marked as correct. If this were not the case, I would probably feel less optimistic about...
I had a physics test last week. When I got the results, there were some correction mistakes in my opinion, so now it's being revised. I had a small disagreement with my professor over one of the theoric exercises, and tomorrow i'll probably be having the same argument again, so I thought of...
