2 identical cars with identically weighted drivers have a head on at 60kph .
Both cars would stop dead in their tracks with neither pushing the other .
Youd naturally say the collision once you calculate both vehicles speeds was at 120kph .
Now up untill there it all makes sense untill you start thinking of another scenario . 1 driver sits on 60 and drives straight into a brick wall to a dead stop , wouldnt this be the same momentum as if in the first head on accident .
This has got me as stumped today as when i start trying to work out how big space is
