Cartesian Vector Question?
So this was a question on my recent vectors test:
Ship is sailing at a heading of 173 degrees at a speed of 35 knots. Wind is blowing from a bearing of 118 degrees at a speed of 16 knots. Determine the resultant speed.
We were asked to use cartesian vectors to solve. (Correct? answer should be 29 knots) Using this method, I get a different answer then if I did cosine law (46 knots).
Can someone show me what is going on with this, and which is truly the correct answer?
-> and yes I know it says FROM a bearing of 118
