1. The problem statement, all variables and given/known data The diagram below shows two vectors, A and B, and their angles relative to the coordinate axes as indicated. DATA: alpha = 42.7 degrees, beta = 60.0 degrees, A = 6.70 cm. The vector A - B is parallel to the -x axis (points due West). Calculate the y component of vector B. 2. Relevant equations SOH CAH TOA 3. The attempt at a solution So I can't figure out what I am doing wrong. I thought I knew these basics!! ARG Anyway I got one chance left. So please let me know if i'm right Well I found the angle of the triangle I am trying to find vecor y for. I am using the right triangle Since the sum vector (A-B) has no y-component, vector A must have the same y-component as vector B. So: 90-42.7=47.3 cos47.3 = x/6.7 6.7 * cos47.3=x Answer: x=4.54367 cm And thats it! BUT NOOOOO its not right ha. Is it suppose to be -4.54367cm because the component y is going y-? Or maybe I am just pig headed and am missing a major part in the problem.
