How Does a Gust of Wind Affect a Sailboat's Speed and Direction?

[Jennifer001]

Homework Statement

a sailboat is traveling east at 5m/s. a sudden gust of wind gives the boat an acceleration of .80m/s^2, 40 degree north of east. what are the boat's speed and direction 6 s later when the gust susides?

I am completely lost on this question.. i don't know how to approach this, can someone get me started?

Impulse is I = $$\Delta p$$ or change in momentum. I is also equal to force times t ( I = F $$\Delta t$$ )
Set the equations equal to each other then work out the x and y components.
