Added final paragraph to answer comment question

| Nov 3, 2011 at 7:11 | comment | added | FrankH | In all these cases the change in speed of each car is 50kmph in a short time so the damages will be equivalent. However, if a car traveling at 100kmph hits an infinite mass wall the change in speed in a short time will be 100kmph so it is not equivalent to the two cases in the previous comment... | |
| Nov 3, 2011 at 7:06 | comment | added | FrankH | Yes, the object will hit at 100kmph but that is irrelevant to the analysis in my answer. A situation which is equivalent is the following: one car sitting stationary (with brakes off) while the other car hits it head on at 100kmph - this would be equivalent to have 2 cars hitting head on at 50kmph. This assumes a perfectly inelastic collision so that the two cars will then proceed (joined together) in the original direction of the 100kmph car but they will both be going at 50kmph. | |

Assuming the object does not decelerate when shattering your front window, that object will indeed hit you at 100kmph. How does that settle with the above answer? | |
