WebbWhile a racing driver who is expecting to have to brake might react in half a second or less, drivers in real life are relatively complacent and reaction times of 1.5-2 seconds are the norm. In older drivers this can be as high as 2.5 seconds. Factors that affect braking distance Brakes Brakes slow a car down using friction. WebbA driver’s age, how awake they are and if they’ve consumed any drugs or alcohol can all influence how quickly it takes them to react. Using a mobile phone rather than concentrating on the road can have devastating …

Webb5 aug. 2024 · The formulae for non-uniform motion are given by Newton’s equation of motion. First equation of motion ⇢ v = u + at. Second Equation of motion ⇢ S = ut + 1/2 (at2) Third Equation of motion ⇢ v2 = u2 + 2as. Some very interesting concepts to see in Non-uniform motion are Stopping distance and Reaction time. WebbDriving when tired, distracted or impaired significantly increases reaction times, so these thinking distances should be thought of as minimums. TRL referred to academic literature and concluded that the average thinking time is 1.5 seconds − more than double the 0.67 seconds set out in the Highway Code. diy box storage shelves
