Aspeeding 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?

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

now we know that

if we will have F = 0

so here we can say

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.

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated

don't remove my answer im trying my best to answer them
