    1. The problem statement, all variables and given/known data
    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 dont know how to approach this, can someone get me started?

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