A ship travelling 55 degrees [W of N] is 65km farther north after 3.0h. What is the ship's velocity.
sin, cos, tan?
The Attempt at a Solution
I know that Vground= Vair + Vwind, and that Vground = Vboat + Vcurrent, but i'm not sure if that is even relevant to the question... So far I have drawn out :
Do I add these vectors together or subtract? and am I trying to find the boat's velocity or ground velocity. I think boat velocity but what does that make of the 55 degrees W of N... I am so lost please help (:
