> Both trains and cars have stopping distances that are proportional to speed Doh. Stopping distance is proportional to the square of speed. I knew this was wrong when I was typing it out, but I convinced myself it was right. I must have been thinking of the time. Being the square of the speed actually makes my point stronger, as the speed doesn't need to be reduced nearly as much to obtain a given stopping distance. |
