Answer:
The Storm Surge of a hurricane
Explanation:
A hurricane can ultimately cause a tsunami and is just as deadly.

Explanation:
<h3>a and b</h3>
We can use the following formula, from kinematics:
![(v_f)^2-(v_i)^2 = 2 \ a \ d](https://tex.z-dn.net/?f=%28v_f%29%5E2-%28v_i%29%5E2%20%3D%202%20%20%5C%20a%20%5C%20%20d)
where
is the final speed,
is the initial speed, a is the acceleration and d the distance traveled.
Knowing that the final speed is zero, and the initial speed is
![v_i = 206 \frac{km}{h} = 206 \frac{km}{h} \frac{1000 \ m}{1 \ km} \frac{1 \ h}{3600 \ s} = 57.22 \frac{m}{s}](https://tex.z-dn.net/?f=v_i%20%3D%20206%20%5Cfrac%7Bkm%7D%7Bh%7D%20%3D%20206%20%5Cfrac%7Bkm%7D%7Bh%7D%20%5Cfrac%7B1000%20%5C%20m%7D%7B1%20%5C%20km%7D%20%5Cfrac%7B1%20%5C%20h%7D%7B3600%20%5C%20s%7D%20%3D%2057.22%20%5Cfrac%7Bm%7D%7Bs%7D)
we obtain
![(0)^2-(57.22 \frac{m}{s})^2 = 2 \ a \ 190 \ m](https://tex.z-dn.net/?f=%280%29%5E2-%2857.22%20%5Cfrac%7Bm%7D%7Bs%7D%29%5E2%20%3D%202%20%20%5C%20a%20%5C%20%20190%20%5C%20m)
![a = \frac{ - \ 3,274.13 \frac{m^2}{s^2} }{ 2 \ 190 \ m}](https://tex.z-dn.net/?f=%20a%20%3D%20%5Cfrac%7B%20-%20%5C%203%2C274.13%20%5Cfrac%7Bm%5E2%7D%7Bs%5E2%7D%20%7D%7B%202%20%5C%20190%20%5C%20m%7D%20)
![a = - 8.617 \frac{m}{s^2}](https://tex.z-dn.net/?f=%20a%20%3D%20-%208.617%20%5Cfrac%7Bm%7D%7Bs%5E2%7D%20)
Now, knowing that
![g = 9.806 \frac{m}{s^2}](https://tex.z-dn.net/?f=%20g%20%3D%209.806%20%5Cfrac%7Bm%7D%7Bs%5E2%7D%20)
then
![a = \frac{- 8.617 \frac{m}{s^2}} { 9.806 \frac{m}{s^2} } \ g](https://tex.z-dn.net/?f=%20a%20%3D%20%5Cfrac%7B-%208.617%20%5Cfrac%7Bm%7D%7Bs%5E2%7D%7D%20%7B%209.806%20%5Cfrac%7Bm%7D%7Bs%5E2%7D%20%7D%20%5C%20g%20)
![a = - 0.8798 \ g](https://tex.z-dn.net/?f=%20a%20%3D%20-%20%200.8798%20%5C%20g%20)
<h3>c</h3>
We can use the following formula
![v(t) = v_0 + a t](https://tex.z-dn.net/?f=v%28t%29%20%3D%20v_0%20%2B%20a%20t)
so
![0 = 57.22 \frac{m}{s} - 8.617 \frac{m}{s^2} \ Tb](https://tex.z-dn.net/?f=0%20%3D%20%2057.22%20%5Cfrac%7Bm%7D%7Bs%7D%20-%208.617%20%5Cfrac%7Bm%7D%7Bs%5E2%7D%20%5C%20Tb)
![Tb = \frac{ 57.22 \frac{m}{s} }{ 8.617 \frac{m}{s^2} }](https://tex.z-dn.net/?f=Tb%20%3D%20%5Cfrac%7B%2057.22%20%5Cfrac%7Bm%7D%7Bs%7D%20%7D%7B%208.617%20%5Cfrac%7Bm%7D%7Bs%5E2%7D%20%7D%20)
![Tb = 6.64 \ s](https://tex.z-dn.net/?f=Tb%20%3D%206.64%20%5C%20s%20)
<h3>d</h3>
![\frac{Tb}{Tr} = \frac{ 6.64 \ s }{ 0.4 s }](https://tex.z-dn.net/?f=%5Cfrac%7BTb%7D%7BTr%7D%20%3D%20%5Cfrac%7B%206.64%20%5C%20s%20%7D%7B%200.4%20s%20%7D)
![\frac{Tb}{Tr} = 16.6](https://tex.z-dn.net/?f=%5Cfrac%7BTb%7D%7BTr%7D%20%3D%2016.6)
