Homework Help: This boat problem is killing me save me

  1. Oct 17, 2004 #1
    A boat travels east at 5.0 m/s. A sudden gust of wind gives the boat an acceleration of (.80m/s^2, 40 degress north of east).
    What is the boat's speed and direction 6.0 s later when the gust subsides.

    Try the equation:

    [tex] V_f = V_i + a * t [/tex]


    Vf= Final velocity
    Vi= Initial velocity

    a= accelration
    t= time

    It didn't work.
    I applied the formula and had 9.8m/s

    There's no way you could've gotten that answer.

    I plugged in the inital and final velocity and the duration of the acceleration which was 6 seconds. The units check out. My results:

    9.2 m/s at 19.5 degrees

    How did you arrive at your solution?
