Two or more variables considered to be related, in a statistical context, if their values change so that as the value of one variable increases or decreases so does the value of the other variable (although it may be in the opposite direction).
And the degree to which two variables vary together determines whether the relationship is strong or weak

Answer:
The bumper will be able to move by 0.01155m.
Explanation:
The magnitude of deceleration of the car in the front end collision.
![a = \frac{F_m}{m} \\](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7BF_m%7D%7Bm%7D%20%5C%5C)
![a = \frac{80000}{1500} \\](https://tex.z-dn.net/?f=a%20%3D%20%5Cfrac%7B80000%7D%7B1500%7D%20%5C%5C)
![a = 53.33](https://tex.z-dn.net/?f=a%20%3D%2053.33)
This is the deceleration of the car that is generated to stop due to a front end collision.
4 km/h = 1.11 m/s
Now, the initial speed of the bumper in the relation of car, Vi = 0
Now, the initial speed of the bumper in the relation of car, Vf = 1.11 m/s
Use the below equation:
![s = \frac{(Intitial \ speed)^2 – (Final \ speed)^2}{2a} \\](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B%28Intitial%20%5C%20speed%29%5E2%20%E2%80%93%20%28Final%20%5C%20speed%29%5E2%7D%7B2a%7D%20%5C%5C)
![s = \frac{(1.11)^2 – (0)}{2 \times 53.33} \\](https://tex.z-dn.net/?f=s%20%3D%20%5Cfrac%7B%281.11%29%5E2%20%E2%80%93%20%280%29%7D%7B2%20%5Ctimes%2053.33%7D%20%5C%5C)
![s = 0.01155 \\](https://tex.z-dn.net/?f=s%20%3D%200.01155%20%5C%5C)
Thus, the bumper can move relative to the car is 0.01155 m .
