1. The problem statement, all variables and given/known data A ship sets sail from Rotterdam, The Netherlands, heading due north at 7.00 m/s relative to the water. The local ocean current is 1.50 m/s in a direction 40.0º north of east. What is the velocity of the ship relative to the Earth? 2. Relevant equations Vr=Vs-Vc r=relative s=ship c=ocean current 3. The attempt at a solution I tried using the equation above but i noticed i needed to get a direction and that is where i am stuck.
