A speeding car collides with a wall (attached to Earth). Consider the car-Earth system to be isolated. A loud sound is produced in the collision, and the car is deformed. What can you say about the momentum of the car-Earth system in this case?

That the total momentum of the system is conserved

Answer:

Momentum of car and Earth as a system will remain conserved

Explanation:

As we know that momentum conservation is applicable when system has no external force on it

So here we will say

[tex]F = \frac{\Delta P}{\Delta t}[/tex]

now we know that

if we will have F = 0

[tex]0 = \frac{\Delta P}{\Delta t}[/tex]

so here we can say

[tex]\Delta P = 0[/tex]

now since Earth and car as a whole system is considered then there is no external force on that system.

So here momentum as a whole will remain conserved.
