Homework Statement
vector a = 100 units at 50.0 degrees vector b = 200 units at 270 degrees. find r, sketch a,b, r.
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!
