1. The problem statement, all variables and given/known data I'm charting vectors graphically and am given: 15m/s at 20 degrees + 6m/s at 90 degrees + 8 m/s at -135degrees. Do I have to convert the m/s into Newtons before graphing? Also, which direction would that -135degrees be in if you start at a point? I have no idea what the negative degrees mean and haven't found help online. 2. Relevant equations 3. The attempt at a solution Tried laying it out similar to if I had N and graphed it to scale, but my numbers were way off.
