q1: a cyclist brakes to a stop. his thinking distance was 1m and his braking distance was 3m. what was his overall stopping distance?
q2: a car driver notices that there is a red light coming up. he brakes and stops in a total distance of 52 metres. if his thinking distance was 15 metres, what was his braking distance?
q3: a car takes 76 metres to stop once a driver has noticed a hazard. if the thinking distance of the driver was 14m and the speed of the car was 8m/s how long did it take the brakes to slow the car down to a stop?
q4: a lorry travels 28m when stopping from a speed of 4m/s. if its braking distance was 18m, what was the driver’s reaction time?
q5: car 1 brakes to a stop on a dry road. car 2 does the same thing, at the same speed, on a road where it has been raining.
