To calculation:
Resultant velocity and direction of watercraft according to observer.
Answer to Problem 26PPS
Resultant velocity is
Explanation of Solution
Given information:
Calculation:
Resultant
Resultant vector is that starts at the beginning o the velocity vector and ends at the tip of the arrowhead of the current.
Now use Pythagoras theorem to find the resulting vector magnitude.
To find vector direction use trigonometry,
Take the inverse of tangent,
Since compass directions start with
Hence, Resultant velocity and direction of watercraft according to observer is
