Is two cars colliding at 50mph the same as one car colliding into a wall at 100 mph? – Physics Stack Exchange

I spent a goodly amount of time watching the Mega Mythbusters marathon over the holidays. BBC America is the channel we have on more than 50% of the time. And, no we aren’t TV junkies.
I love seeing how things work and most of all how people solve problems. Being an aging hippy, I remember garages with workbenches. Pegboard loaded with tools neatly organized on a background of stenciled outlines. Gerber baby jars, shelves of them, holding every kind of screw, nut, bolt, thingamajig, whatsit, doo-hickey ever made. It seemed like everyone had their own personal Home Depot in their garage. Things could be fixed back then and someone always knew how. Mythbusters workspaces remind me of that. A tinkerers paradise.

That’s not really my point here (it does open creaky doors, memories of a long time past)
I was looking for an answer to one of their myths in which they gave an incorrect conclusion.
I ended up at the site linked to above. I had never heard of it. I am posting here only because the QA about the MB question was actually civil and informative. If the other blogs are similar this looks to be promising. Do read on if you haven’t already and if you have, keep enjoying!
