Week of 3/12

Like usual nobody attended my wednesday office hours. People did attend my friday office hours. We got through some problems but unfortunately this time my explanations did not make sense to him. He kept thinking you needed a mass for an external force when the force was already given and he couldn't make sense of it. Other than that problem he was fine with all the other ones. The other person who came in we were able to get through 2 of her three problems and I set her up on solving the third one.
