A canoe has a velocity of 0.550m/s southeast relative to the earth. The canoe is on a river that is flowing at 0.540m/s east relative to the earth.
Alright so I attempted many different things an still do not understand the nature of the question nor do I understand how to get an answer. Find the magnitude of Vc/r of the canoe relative to the river now the next question Find the direction of the velocity of the canoe relative to river expressed as an angle measured south of west. Now I figured that the angle would be equal to theta if you laid our the vectors tail to tip with -Vr/e + Vc/e however I have no earthly idea on how to calculate this other than the equation: arcsin(Ay/A with the resulting vector of -Vr/e + Vc/e being defined as A and Ay being the y component of A but im not sure how to calculate the y component of A. If this question doesn't make much sense I apologize I am struggling with the concept as a whole.
