A driver sees a hazard ahead and makes an emergency stop.
State what is meant by the thinking distance.
The reaction time of the driver is 0.70 s and the car is travelling at 20 m/s. Calculate the thinking distance.
The braking distance of the car at this speed is 30 m. Calculate the stopping distance.
Explain why the stopping distance would be greater if the driver had been travelling at 30 m/s.
