It decreases because it gave its momentum to the other car.
Explanation:
because it doesn't depend upon other unit like kg meter and second
Vapor is usually made with water and it would be made with gas.
A=f/m
A=900/425
A=2.18
To determine acceleration you divide the force by the mass.
Newton's first law of motion says something like "An object remains
in constant, uniform motion until acted on by an external force".
Constant uniform motion means no change in speed or direction.
If an object changes from rest to motion, that's definitely a change
of speed. So it doesn't remain in the state of constant uniform
motion (none) that it had when it was at rest, and that tells us
that an external force must have acted on it.
