Question
A ship is heading north at 15km/h in a tide moving at 6km/h westward. Determine the magnitude and direction of the resultant velocity of the ship.
I can't answer it because I don't get the formula. And please give me the formula. I need the answer later. I'll wait! Thankyou in advance!

You have 2 vectors: one pointing north and one pointing west.
Vr = -6 + 15i = 16.2km/h[-68.2o] = 16.2km/h[68.2o] N. of W.
Vr = -6 + 15i = 16.2km/h[-68.2o] = 16.2km/h[68.2o] N. of W.
