Answer:
The force exerted by the ocean tide is directed to the right (east).
The force exerted by the wind is directed to the northwest (45° N of W).
We should separate the x- and y- components of the wind force, and evaluate each component separately.
We denote the direction to the right as the positive direction, so the x-component of the wind force is in the negative direction.
The resultant force is as follows:
The resultant acceleration can be found by Newton's Second Law:
The magnitude of the resultant acceleration is
