Answer:
The deceleration of the plane is [tex]3.38\ m/s^2[/tex].
Explanation:
Given that,
The planes velocity before the crash was 2000 yards per second
1 yards per second = 0.9144 m/s
2000 yards per second = 1828.8 m/s
Finally it crashes, its final speed will be 0.
It takes 9 minutes or 540 seconds. It will decelerate as the final speed is less than initial speed. So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{0-1828.8}{540}\\\\a=-3.38\ m/s^2[/tex]
So, the deceleration of the plane is [tex]3.38\ m/s^2[/tex].
