Car moving at constant speed 100km/h

No.

engineering at its best.

After crash speed is 0 so in acceleratin hahha

>has no acceleration

Uhh, dude.

But he's right.

Then explain it otherwise you're a brainlet.

Acceleration is defined as the change in speed divided by change in time. If the car has a velocity and then after the crash no velocity, then there is also a timeframe in which this has happened. Thus it has acceleration. What a shitty bait thread.

Yes. Constant velocity, no acceleration.

Right, and then it crashed, so that constant velocity changed. So it underwent an acceleration (deceleration is acceleration in a particular direction).
