112. The stopping distance of a car, [tex]\( s \)[/tex], is given by the equation below.

[tex]\[ s = \frac{v^2}{a} \][/tex]

In this equation, [tex]\( v \)[/tex] is the car's velocity and [tex]\( a \)[/tex] is the acceleration due to gravity.

The stopping distance of the car:

A. Increases linearly
B. Increases quadratically
C. Decreases linearly
D. Decreases logarithmically


Sagot :

To determine how the stopping distance [tex]\( s \)[/tex] changes with respect to the car's velocity [tex]\( v \)[/tex], let's analyze the given equation:

[tex]\[ s = \frac{v^2}{a} \][/tex]

where [tex]\( s \)[/tex] is the stopping distance, [tex]\( v \)[/tex] is the velocity, and [tex]\( a \)[/tex] is a constant representing the acceleration.

1. The relationship shows that [tex]\( s \)[/tex] is directly proportional to [tex]\( v^2 \)[/tex].
2. As [tex]\( v \)[/tex] increases, [tex]\( v^2 \)[/tex] will increase as well.
3. Therefore, since stopping distance [tex]\( s \)[/tex] is directly proportional to the square of the velocity [tex]\( v \)[/tex], any increase in [tex]\( v \)[/tex] will result in an increase in [tex]\( s \)[/tex].
4. Specifically, because [tex]\( s \)[/tex] depends on [tex]\( v^2 \)[/tex], this is a quadratic relationship.

So, as the car's velocity [tex]\( v \)[/tex] increases, the stopping distance [tex]\( s \)[/tex] increases quadratically.

Thus, the correct answer is:
B) Increases quadratically
