A motorist drives south at 32.0 m/s for 4.00 min, then turns west and travels at 55.0 m/s for 5.10 min, and finally travels northwest at 12.0 m/s for 2.00 min. Find the following values. 1.total vector displacement (m) at a _ degree south of west 2.average speed (m/s) 3. average velocity m/s (magnitude) at a _ degree south of west. I'm not too sure how to approach this problem at all? Any hints would be appreciated, thank you!
