Week of 9/24

I had eight people in my office hours on Tuesday for both 0110 and 0174. The biggest problem in the 0174 crowd seemed to be the force on three boxes problem that we did in lecture this week. I also had one person today with a couple of conceptual questions before the first midterm. The biggest problem overall seems to be finding a good systematic approach to kinematics problems, although another common issue I am running into is a lack of understanding of vector addition and subtraction, which has caused issues with more complicated kinematics problems as we have moved deeper into the semester.
