Two cars collide in a parking lot. Before the collision, their total momentum was 1800 kg m/s to the east. What is their total momentum after the collision.

Respuesta :

During collision there is no force on two cars together

So here we can say

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

Since force on the system is zero

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

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

[tex]P_i = P_f[/tex]

So after collision momentum will remain the same i.e. 1800 kg m/s
