Not entirely true. After colliding with a stationary car the previously moving car will retain some of its velocity. That will then dissipate over time and be less violent.
So to some extent - when simplified, to a first approximation - you really can switch frames of reference like that.
- modeless 16y agoWhen simplified, yes, but if you start talking about projectiles then you are explicitly not simplifying things, and should also account for the effect of the ground because it's probably a larger concern than projectiles in a collision like this.
