Construct a coordinate system with the y-axis pointing North and the x-axis pointing East. You must transform the courses into angles with respect to the x-axis!
The way of the ship is a straight line:
Expand the values in the direction vector and use rounded decimals:
The way of the boat (the 2nd vessel!) is:
The norm of the direction vector represents the speed of the boat:
The angle with respect to the x-axis is:
Since the direction vector is pointing into the 4th quadrant the boat is heading
To answer the second question calculate the point of intersection between the two lines:
I've got t = 5.99 and r = 0.48
And what does that mean?
