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:

V_f = V_i + a * t


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?
