The Attempt at a Solution
My attempt is in the attached image.
I tried to leave the numbers out until the end. I have not written the exact working as I did it in draft elsewhere. I used the Law of Cosines on the vector triangle, in order to obtain [itex] \vec v_{A/B} [/itex], which came out as 2.057544... m/s. But that is not the correct answer.
Upon reflection, I have realized that I was supposed to draw the vector triangle such that the angle between [itex] - \vec v_{B} [/itex] and [itex] \vec v_{A} [/itex] is obtuse. How should one decide on how to draw the vector triangle?
Many thanks.
