Four students came to my office hours on Wednesday. They mostly had questions regarding a really difficult problem on the homework. It asked how high a block would slide up a ramp if they were both on a frictionless surface, and the block was originally traveling at some velocity, v. The problem was difficult because the ramp would start to move as soon as the block hit it, making the calculations more difficult. We broke the problem into different parts and ended up making sense of it.
No students came to office hours Thursday or Friday. The class has an exam on Wednesday, so hopefully everyone does well!
