Well, I think it kinda depends on how long the "extended period" is.
If the extended period is a week, a month, or a few months,
then I'd call it a 'cold wave'.
If the extended period is like 100 years or more, then you're
starting to talk 'ice age'.
Both cars are canceling out the energy of each other. The energy that is left over because one car has a bigger kinetic energy is the energy that is going to move BOTH the cars.
First Car : <em>0.5 * 2000kg * 3m/s^2 = 10.24 KJ</em>
Second Car :<em> 0.5 * 2000kg * 2m/s^2 = 4 KJ</em>
Leftover Energy : <em>10.24 KJ - 4 KJ = 6.24 KJ
</em>
Movement of BOTH cars :<em /><em>
6.24 = 4000kg * v^2
</em>v = √(6.24 / 4000) =0.04 m/s = 4 cm/s
