Assuming the driver was paying attention to the road, even taking ~2 seconds (About how long it took me to clearly recognize the truck in the video) and slowed down from 70MPH from 40MPH, it would reduce amount of kinetic energy in the collision by ~300%. It could be the difference between a survivable accident and a lethal one.
- robotresearcher 5y agoA 100% energy reduction would leave zero energy. 300% doesn’t make sense.
- zopa 5y ago7^2 is 49, 4^2 is 16, all the other factors cancel. Yes, of course the right way to say it is "reduces the energy by 67%," but it's not that hard to see what was meant.
