Moderator Cynic Posted October 17, 2014 Moderator Posted October 17, 2014 So finding out 120mph into reinforced concrete is bad is a shock because.....?
AndrewElvisFan Posted October 17, 2014 Posted October 17, 2014 I think the point they are making is that 2 cars travelling at 60mph involved in a head on would have the same impact. Even still, shouldn't be a shock!
Moderator Cynic Posted October 17, 2014 Moderator Posted October 17, 2014 Nope. Owing to the properties of large lumps of concrete and some clever maths. The car hitting concrete has to absorb all of its own kinetic energy. When 2 cars hit head on assuming the same mass they each absorb their share. Therefore a car hitting a car head on of the same mass is actually identical to 1 car hitting a concrete block at the same speed. Be it 40, 60, 100mph. 1
