Can someone please help me with these 2 questions
1) 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?
2) 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?
