Not to mention it is perfectly possible to have a nasty crash at 50KPH.
Especially if you hit an object moving towards you, which greatly
increases the kinetic energy released. But you forget, Savageduck -
Macaw is a special snowflake. His life and physics itself works
different for him.
If you're not part of the solution, you're part of the precipitate.
Oh no not another idiot who flunked physics. 30mph into an identical car doing 30mph in the opposite direction is the same, PRECISELY the same, as a 30mph car into an immovable concrete wall. You decelerate from 30mph to 0mph in the same time. Your kinetic energy loss is the same. The other car has the same kinetic energy, but that goes to damaging him, not you.

Says the guy who put me in his killfile then replied to me straight afterwards!!! You're either stupid or a liar.
And if you think the physics I've written is wrong, feel free to correct it. Or go discuss it in a physics newsgroup and get laughed at.
Create instant designer stubble by sucking a magnet and dipping your chin in a bowl of iron fillings.
you're once again showing your ignorance.
two similar sized vehicles traveling at 30 mph that collide head-on is
equivalent to a collision of one hitting a brick wall at 30 mph.
it's simple math.
What you say sounds like it's probably right and I was wrong. Assuming
that you are correct, my apologies for the error. But none of us is
perfect, not even you, and we all make mistakes from time to time.
But not all of is as nasty as you are. Just because I got something
wrong is not an excuse for your nastiness and rudeness.
And by the way, you have no idea whether I've ever taken a physics
class or flunked it.
i didn't say identical. i said both are damaged.
if a small car and an 18 wheeler truck collide, both will sustain
even a concrete bridge will sustain some damage if a car crashes into
it. it'll be minor but it won't be zero.
In that case you DO add the mph. For the car. The truck doesn't really get hurt.
It'll be as good as damnit zero. And it's a common thing to crash into. 70mph (the speed limit, like anyone goes that slow) into a bridge support is just as bad as 70mph into someone going 70mph the other way. Some people actually believe you'd have to hit the bridge at 140mph to have the same damage to your car.
