1. The problem statement, all variables and given/known data 1. The problem statement, all variables and given/known data A man walks 5 m at 37degrees north of east and then 10 m at 60degrees west of north. What is the magnitude and direction of his net displacement The answer is around 9.3m at around 120 degrees angle on the +x axis 2. Relevant equations 3. The attempt at a solution Well my question is I try to solve this component using the component way This is my work http://imageshack.us/photo/my-images/802/vectorsproblem2question.png/ My question is that for vector B the ax is sin60(10)=8.66 so when I do my i j notation can I put -8.66 since it's pointing towards west which is going towards the negative x coordinate? Thank you guys for the help.
