P5: Quiz 18 – Answers
1)
a) Stopping distance = thinking distance + braking distance
b) The stopping distance of a vehicle is the distance covered between a driver noticing a hazard and the vehicle becoming stationary
2)
a) Thinking distance is the distance travelled between the driver noticing the hazard and pressing the brakes (acting on the hazard)
b) Any two from speed of a vehicle, alertness, tiredness, alcohol, drugs or any other factors that affect the reaction time of an individual
3)
a) The braking distance is the distance that a vehicle travels whilst the brakes are applied
b) Any two from speed of a vehicle, quality of the brakes, the road surface, amount of grip on the tyres/ tyre tread, weather conditions etc.
4) Stopping distance is the sum of the thinking distance and the braking distance. A greater speed increases both the thinking distance and the braking distance, which therefore increases the stopping distance. Therefore, the stopping distance will be greater when the car is travelling at 25 m/s
5) 35 metres

Questions
1) The stopping distance of a vehicle is made up of two different components.
a) What is the calculation for working out the stopping distance of a vehicle?
b) Define the stopping distance for a vehicle.
2)
a) Define thinking distance.
b) Give two factors that affect thinking distance.
3)
a) Define braking distance.
b) Give two factors that affect braking distance.
4) For the same vehicle, would the stopping distance be greater if the vehicle was traveling at 10 m/s or at 25 m/s. Explain your answer.
5) A car is travelling at a speed of 20 m/s. The thinking distance when travelling at this speed is 16 metres and the braking distance when travelling at this speed is 19 metres. Calculate the stopping distance when the car is travelling at 20 m/s.
