Homework Statement
A sailboat is traveling east at 5.0 m/s. A sudden gust of wind gives the boat an acceleration of 0.80 m/s^2 at 40 degrees north of east. What are the boat's speed and direction 6.0 s later when the gust subsides?
Homework Equations
xf=xi+vix(delta t)+1/2ax(delta t)^2
vfx=vix+ax(delta t)
The Attempt at a Solution
This is really giving me a tough time.
I started by trying to determine the velocity of both the x and y values.
vfx=vix+ax(delta t)
vfx=5m/s+(0)(6)
vfx=5m/s
vfy=5m/s+(.8)(6)
vfy=9.8 m/s
v=sqrt(vx^2+vy^2)
v=sqrt(5^2+9.8^2)
v=11.002 m/s
I really need help determining the position after 6s.
