A physics question: I was in a car collision recently and the other party alleges that the impact was such as to push his car 3 metres sideways (ie at 90 degrees to wheels). Assuming that both cars weighed a tonne and he was stationery (actually turning across me very slowly) then is it possible to calculate the speed I was doing at impact? I think it was below 20mph but the suggestion is that I was speeding. I know f=ma but newton gets involved and I am lost!
