1. The problem statement, all variables and given/known data 2. Relevant equations a=(v2-v1)/t 3. The attempt at a solution I used the vector between the point before A and A as my v2. I used the vector between the point two before A and the point before A as my v1. I put them tail to tail and he resultant vector looks like (E) in the image. Is this how I'm supposed to do these problems?
