Answer:
2) 433 mph
Explanation:
The final velocity of the raindrop as it reaches the ground can be found by using the equation for a uniformly accelerated motion:
![v^2 = u^2 + 2ad](https://tex.z-dn.net/?f=v%5E2%20%3D%20u%5E2%20%2B%202ad)
where
v is the final velocity
u = 0 is the initial velocity (the raindrop starts from rest)
a = g = 9.8 m/s^2 is the acceleration due to gravity
d = 2 km = 2000 m is the distance covered
Solving for v,
![v=\sqrt{u^2 +2gd}=\sqrt{0^2+2(9.8 m/s^2)(2000)}=198 m/s](https://tex.z-dn.net/?f=v%3D%5Csqrt%7Bu%5E2%20%2B2gd%7D%3D%5Csqrt%7B0%5E2%2B2%289.8%20m%2Fs%5E2%29%282000%29%7D%3D198%20m%2Fs)
And keeping in mind that
1 mile = 1609 metres
1 hour = 3600 s
The speed converted into miles per hour is
![v=198 \frac{m}{s}\cdot \frac{3600 s/h}{1609 m/mi}=433 mph](https://tex.z-dn.net/?f=v%3D198%20%5Cfrac%7Bm%7D%7Bs%7D%5Ccdot%20%5Cfrac%7B3600%20s%2Fh%7D%7B1609%20m%2Fmi%7D%3D433%20mph)
