## Homework Statement

A sailboat is traveling east at 5.1m/s . A sudden gust of wind gives the boat an acceleration = (0.80 m/s

^{2}}, 40° north of east).

What is the boat's direction 6s later when the gust subsides?

## Homework Equations

V

_{f}= V

_{0}+ at

## The Attempt at a Solution

To solve I simply created X and Y components of the velocity after those six seconds, in order to use the arctan function to then find my angle:

V

_{fx}= V

_{ox}+at

V

_{fx}= 5.1 m/s + (6s)* (0.80cos40) = 8.777013327 m/s (x)

V

_{fy}= 0 m/s +(6s) * (0.80sin40) = 3.085380526 m/s (y)

To find the angle, I then simply input these values into the arctan function:

tan

^{-1}(vy/vx) = θ

tan

^{-1}(3.085/8.777) = 19°, north of east

This answer, however, is incorrect. Do you have any advice on my approach, or anything that I may be negating my calculations?
