Define the thinking distance, braking distance and stopping distance of a moving vehicle

Which of the below equations for the stopping distance of a vehicle is correct?Stopping distance = thinking distance – braking distanceStopping distance = braking distance – thinking distanceStopping distance = thinking distance × braking distanceStopping distance = thinking distance + braking distance2What is the approximate reaction time of the average person?0.007 s0.07 s0.7 s7 s3Which of the following factors does NOT affect the thinking distance?The velocity at which the vehicle is travellingThe type of road surfaceHow tired the driver is feelingWhether or not the driver has consumed alcohol or drugs4Which of the following factors does NOT affect the braking distance of a car?The condition of its brakes and tyresDistractions (such as talking to a passenger or using a phone)The size of the braking forceThe weather conditions5(HT) Calculate the resultant force which is required to uniformly decelerate a car of mass 2000 kg to rest from an initial velocity of 20 m/s over a period of 10 seconds.4 kN400 kN40 kN4000 kN6The braking distance of a vehicle is proportional to the square of its initial velocity.  If a vehicle has a braking distance of 10 metres when travelling at 15 mph, what will its braking distance be when it is travelling at 30 mph?20 m40 m100 m50 m

Which term refers to the distance a vehicle travels from the moment the driver applies the brakes until the vehicle comes to a complete stop?

Which of the following factors does NOT affect the thinking distance?The type of road surfaceHow tired the driver is feelingWhether or not the driver has consumed alcohol or drugsThe velocity at which the vehicle is travelling

When brakes are applied to a moving vehicle, the distance it travels before stopping is called stoppingdistance. It is an important factor for road safety and depends on the initial velocity (v0) and thebraking capacity, or deceleration, –a that is caused by the braking. Derive an expression for stoppingdistance of a vehicle in terms of v0 and a

How does it relate to stopping distance?
