Thu, 24 March 2005 04:32 Indi wrote on Thu, 24 March 2005 15:28 Norbie wrote on Thu, 24 March 2005 14:51 As for the original question, if two cars travelling at 50km/h collide head-on the impact will be the same as one car travelling at 50km/h hitting a solid object (eg concrete wall). In other words, hitting another car at the same speed is the same as hitting a solid object. I disagree, think about it if one car is travelling at 50kms and another is approaching it at 50kms the distance between them is decreasing by 100kms therefore their velocity relative to one another will be 100kms. If a car is travelling at 100kms towards a stationery wall its velocity relative to the wall is 100kms so yes it would be the same. For confirmation see Margaret Wertheim's "Pearly Gates of Cyberspace" page 169. i concur! [Report message to a moderator]
