He must've been looking at the nose of the caravan when he said 60, ...

Now, to use an extreme example to make a point, suppose you have a Smart Car in a head on at 60 mph with with a cement truck. The Smart Car will end up going in the opposite direction, that is, backwards, at the instant after impact. So it will be a greater force to the Smart Car than hitting a wall at 60. The cement truck driver, if he was on his cell phone or sneezing at the time of impact, I suppose may only think he hit a deer or raccoon.

When you hit a wall at 50 mph it pushes back with the same energy as another car exactly like yours moving at 50 mph, otherwise the wall would move.

RML is correct, the kinetic energy of each vehicle is (m*v^2)/2. After the collision, all that energy will be conserved, either as the continued motion of one or both vehicles or as damage (absorbed energy) to one or both vehicles. If the vehicles are of different masses and/or traveling at different speeds, one may absorb more or less energy than it contributes.

The only way the car "doing 60 mph" did that little of damage, was if the beer/cigar car was doing 60+ mph. Max. impact looks more like 30 mph OR LESS. The beer and cigars seemed to have gotten lost in this story. |

SOOOOOOOOOO, do we have any takers here to do some high speed tests? Head on with 2 W123, or W126. Head on into a wall, etc.......... then see what the out come will be. Also all depends on the amount of structural rust, if one is rusty and the other isn`t to the amount of damage. How about a head on with a Smart car and a 126? either way here, the Smart car might survive, the driver wont. the W126 will fare better. Any way, it sucks you got hit, at least you were not hurt, and the Cigars and beer didn`t get damaged. Once you get in there checking the damage, hope it isn`t as bad as it looks and get her back on the road. Charlie

sooo does that prove anything?
mass/inertia is transferred into the smart... unequal masses. would it bounce and flip if it hit a wall? |

cop should protect you from taking pics of the driver, but not of the accident damage, including the damage to the other vehicle. how are you going to show serious mental anguish and personal injury with only the damage from your superb vehicle as examples?

Find out where his vehicle was taken and go there and get pics.

You can address collisions with the conservation of momentum. The momentum of a system does not change through the process of a collision. From this you can also say that the velocity of the center of mass of the system does not change through the collision process. (ideally speaking. In reality, you have braking, skidding, etc. that affect the velocity & momentum.
Consider 2 cars, moving in opposite directions. Equal mass: Momentum of A = Ma * Va = 2000 kg * 50 m/sec = 100000 kg *m/sec Momentum of B = Mb * Vb = 2000 kg * -50m/sec (opposite direction, equal speed) = -100000 kg * m/sec The momentum of the system = (100000 -100000 ) kg * m/sec = 0 Unequal mass, equal & opposite speed: Momentum of A = Ma * Va = 2000 kg * 50 m/sec = 10000 kg * m/sec Momentum of B = Mb * Vb = 1000 kg * -50 m/sec = -50000 kg * m/sec Total momentum, before & after collision of the system: (100000-50000) m/sec = 50000 kg *m/sec Velocity of the system = momentum / mass velocity = 50000 (kg m*/sec)/3000 kg = 16.7 m/sec Velocity change for the heavy car = (50 - 16.7) m/sec = 33 m/sec Velocity change for the light car = (-50-16.7) m/sec) = 66.7 m/sec So in this case it hurts to be in the small car. This neglects so many aspects of a collision, but fundamentally conservation of momentum applies.
