ANSWER:

B. -6.25 kg* m/s

STEP-BY-STEP EXPLANATION:

Given:

Mass of car (m) = 0.25 kg

Speed of the car before the collision (v1) = 20 m/s

Speed of the car after the collision (v2) = - 5 m/s

Then we calculate the change of momentum as follows:

[tex]\begin{gathered} p=m\Delta v \\ \\ \text{ we replacing} \\ \\ p=0.25\cdot\left(\left(-5\right)-20\right) \\ \\ p=-6.25\text{ kg*m/s} \end{gathered}[/tex]

The correct answer is B. -6.25 kg* m/s
