geometric and cartesian vectors

(a) A fishing boat sets its course at a heading of S70°W, with a speed of 30 knots. The water current is flowing from a bearing of S60°E, at 7 knots. Determine the resultant velocity of the fishing boat using 2 different methods (one with geometric vectors, the other with cartesian vectors)



(b) Another fishing boat can travel at a maximum speed of 25 knots. This fisherman wants his resultant direction to be exactly west. Assuming the same water current from above:

  1. (i) On what heading should this fisherman set his course so that his resultant velocity is due west?
  2. (ii) How long will this fisherman take to get to his favourite fishing spot which is 18 km west of his current location?
  3. For Part (b), you can use either method to solve.
