1. The problem statement, all variables and given/known data I attached the problem with my attempt. I think the geometry I used is correct but I am getting the wrong answer. When I take the flip Va/V (as shown in my attempt) I get the right answer. I am not even sure if I can relate velocity with a triangle. The method I used is based on the fact that Sa + Sb = L1 so when you take the time derivative you get Va = -Vb.
