1. The problem statement, all variables and given/known data vector a = 100 units at 50.0 degrees vector b = 200 units at 270 degrees. find r, sketch a,b, r. 3. The attempt at a solution The part I don't understand is the 270 degrees. Doesn't this cause vector b to lay on the -y axis? I've tried this question and another one like it: vector a = 10 units at 40 degrees and vector b = 25 units at 180 degrees. Answers given for #1: 139 units at 62.4 degrees or 139 units at 297.5 degrees #2: 18.5 units at 20.4 degrees above -x axis, or 18.5 at 159.7 degrees This is the first physics class I have ever taken in my life. Help is greatly appreciated!
