1. Which of the following best defines stopping distance?
- A. The total distance travelled from when the driver first sees a hazard until the vehicle comes to a complete stop
- B. The distance travelled by the vehicle whilst the brakes are being applied
- C. The distance travelled during the driver's reaction time only
- D. The distance the vehicle travels after the brakes have been fully released
2. A driver is travelling at 20 m/s when they see a red traffic light. Which factor would NOT directly affect their thinking distance?
- A. The driver's reaction time
- B. The vehicle's mass
- C. The speed of the vehicle
- D. The driver's age and alertness
3. Two identical cars travel on the same road in identical conditions. Car A travels at 20 m/s whilst Car B travels at 40 m/s. How does the braking distance of Car B compare to Car A?
- A. It is twice as large
- B. It is four times as large
- C. It is half as large
- D. It is the same
4. A car with worn brake pads and worn tyres travels on a wet road. Which of these factors would increase the braking distance? (HT)
- A. Only the worn brake pads
- B. Only the wet road conditions
- C. The worn brake pads and worn tyres, but not the wet road
- D. All three factors: worn brake pads, worn tyres, and wet road conditions
5. A car of mass 1500 kg undergoes an emergency stop with a deceleration of 8 m/s². Calculate the braking force acting on the car and explain why such large decelerations can be dangerous.
- A. 12 000 N; large decelerations cause the car to slide uncontrollably
- B. 12 000 N; large decelerations can cause injury to occupants due to sudden forces and may cause loss of vehicle control
- C. 187.5 N; large decelerations consume too much fuel
- D. 120 000 N; large decelerations cause the engine to stall
