the question i am workinflg on is:
A ship is required to travel south at a speed of 20km/h. There is a current of 6km/h from the southwest
I am trying to work out the direction the ship must head to compensate for the current and the speed the ship must travel in order to achieve its speed of 20km/h.
I have started by looking at the vector current and calculating its i and j components which i found to be each 6/sqrt2.
I am a bit stuck now and would really appreciate some help, thanks!
