Answer:
[tex]D=kV^2[/tex]
Step-by-step explanation:
In this problem, it is given that,
The stopping distance, D, in feet of a car is directly proportional to the square of it's speed, V.
We need to write the direct variation equation for the scenario above. It can be given by :
[tex]D\propto V^2[/tex]
To remove the constant of proportionality, we put k.
[tex]D=kV^2[/tex]
k is any constant
Hence, this is the required solution.
