A yacht is sailing through water that is flowing due west at 2m/s. The velocity of the yacht relative to the water is 6m/s due south. The yacht has a resultant velocity of V m/s on a bearing of theta. Find V and theta
First we make a sketch of the situation. Then we notice that V can be found by using Pythagoras. Finally, we find theta using the definition of a tan.
