Question 251
3 marks · Easy
Answer and see the solution →Describe how the following factors each affect a car's braking distance.
Factor Speed of the car Condition of the tyres Mass of the vehicle Give a brief explanation for each factor.
Question 252
3 marks · Normal
Answer and see the solution →A cyclist travels along a road on a foggy morning. Suddenly, a dog runs out in front of them. The cyclist has good brakes and new tyres, but still almost hits the dog.
Explain two reasons, using your knowledge of physics, why the cyclist nearly failed to stop in time. (3)
Question 253
3 marks · Normal
Answer and see the solution →A car and a heavy lorry both apply their brakes with the same force while travelling at the same speed on a dry road. The lorry travels further before stopping.
Explain why the lorry takes longer to stop than the car, even though the braking force is the same.
Question 254
2 marks · Normal
Answer and see the solution →State two factors (other than the speed of the vehicle) that can increase the thinking distance of a driver.
Question 255
2 marks · Normal
Answer and see the solution →State what is meant by (a) thinking distance, and (b) braking distance of a vehicle.
(a)[1 mark]State what is meant by thinking distance.
(b)[1 mark]State what is meant by braking distance.
Question 256
3 marks · Normal
Answer and see the solution →A driver is travelling at night when it begins to rain heavily. Describe and explain how both the thinking distance and the braking distance are affected, giving a reason for each.
Question 257
3 marks · Normal
Answer and see the solution →The table below shows the stopping distances for a car with good tyres and brakes on a dry road:
Speed (mph) Thinking distance (m) Braking distance (m) Total stopping distance (m) 30 9 14 50 15 38 (a) Complete the table by calculating the total stopping distance for each speed.
(a)[2 marks](b)[1 mark](b) Use the table to state how the total stopping distance changes as the speed increases.
Question 258
4 marks · Normal
Answer and see the solution →Explain how each of the following factors affects the braking distance of a vehicle. (a) The mass of the vehicle (b) The speed of the vehicle (c) The condition of the road surface (d) The condition of the tyres
(a)[1 mark](b)[1 mark](c)[1 mark](d)[1 mark]Question 259
4 marks · Normal
Answer and see the solution →A van is travelling along a dry road at 40 mph. The thinking distance is 12 m and the braking distance is 24 m.
(a)[1 mark]Calculate the total stopping distance for the van.
(b)[2 marks]If the driver was distracted, the reaction time would increase. Explain what would happen to the stopping distance.
(c)[1 mark]The braking distance would remain the same. Explain why.

1 mark · Normal
Answer and check →Which of the following would NOT increase the stopping distance of a car?
- A.Well-inflated tyres with deep tread
- B.Wet and icy road surface
- C.Driver is tired
- D.Increased vehicle speed
