help....The Vector Nature of Newton's Seond Law of Motion

A 350-kg sailboat has an acceleration of 0.62m/s2 at an angle of 64 degress north of east. Find the magnitude and direction of the net force that acts on the sailboat.

I have f=ma to find the force.
F=350(0.62)
F=217N

Then i'm not really sure about the magnitude and direction.

I believe you have to decompose the vector. You have to find $$F_{x}$$ and $$F_{y}$$ using the relationships $$F_{x} = F\cos\theta, F_{y} = F\sin\theta$$. You are already given the net force.
