1. The problem statement, all variables and given/known data A plane must fly to a destination located due north from its departure point. A gentle wind is blowing from the south-west. What direction must the plane point to reach its destination? 2. Relevant equations 3. The attempt at a solution http://i.minus.com/iMPPjrIF6APd.png [Broken] In situation 1 I drew the displacement if the plan was to fly due north. In situation 2 I drew the displacement if the plane was to fly north-west. I'm not really sure, but I think that sit. 2 might be what happens if the plane wanted to reach its destination.
