Answer:
0kgm/s
Explanation:
Given parameters:
Mass of the passenger = 48.5kg
Unknown:
Momentum = ?
Solution:
The momentum of a body is the quantity of motion a body possesses. A body not in motion has no momentum.
Mathematically;
Momentum = mass x velocity
So;
Since the train is stopped, velocity = 0m/s
Momentum = 48.5 x 0 = 0kgm/s
As it is given that Bulk modulus and density related to velocity of sound
![v = \sqrt{\frac{B}{\rho}}](https://tex.z-dn.net/?f=v%20%3D%20%5Csqrt%7B%5Cfrac%7BB%7D%7B%5Crho%7D%7D)
by rearranging the equation we can say
![B = \rho * v^2](https://tex.z-dn.net/?f=B%20%3D%20%5Crho%20%2A%20v%5E2)
now we need to find the SI unit of Bulk modulus here
we can find it by plug in the units of density and speed here
![B = \frac{kg}{m^3} * (\frac{m}{s})^2](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7Bkg%7D%7Bm%5E3%7D%20%2A%20%28%5Cfrac%7Bm%7D%7Bs%7D%29%5E2)
so SI unit will be
![B = \frac{kg}{m* s^2}](https://tex.z-dn.net/?f=B%20%3D%20%5Cfrac%7Bkg%7D%7Bm%2A%20s%5E2%7D)
SO above is the SI unit of bulk Modulus
I believe the answer is B
