Maybe we dont care. Maybe the driver didnt care when the car hit the tree. Damn that it was 155mph, I wish it was 155kmph.
155 kmph is approx 40 meters per sec. A car that weights about 900 kg and hits a tree withthe speed of 40 meters per sec will transform approx 0.7Mj of kinetic energy to heat. That amount of energy could turn 1.8 kg of water from 1C to 99C. But how cares
