Show answer
Correct answer
- BSí; a mayor velocidad, mayor probabilidad de sufrir lesiones graves.Yes; the higher the speed, the higher the chance of serious injuries.
Explanation
The higher the speed, the more energy has to be absorbed in the crash, and this energy grows with the square of the speed. That is why both the chance of having a crash and the seriousness of the injuries increase; passive safety systems reduce injuries but do not cancel out the effect of speed.
