Answer:
-14 m/s
Explanation:
Saki's initial velocity is:
where we put a negative sign because the problem tells us to use a coordinte system in which rightward is positive, while Saki's initial velocity is towards the left.
Saki's acceleration due to the breeze is:
Where again, we put a negative sign since the acceleration is leftward.
In order to find Saki's velocity after t = 6 s, we can use the following equation:
And substituting all the numbers, we get
and the negative sign means the new velocity is leftwards.
