Question 4778
One of the consequences of speed is that as it increases...
- coordination of movements is lost.
- the greater the severity of injuries in an accident.
- reaction time is reduced.
Show answer and explanation
Correct answer: the greater the severity of injuries in an accident.
In a crash, the vehicle releases its energy all at once, and that energy increases with the square of its speed. Going at 130 km/h instead of 100 means 69% more energy, which is why injuries are more severe. Driving faster doesn't shorten your reaction time.
