The driver of a vehicle approaching a signalised intersection at a speed of 40 kmph applied brakes on seeing the signal changing from green to amber and the vehicle was brought to stop on the prescribed stop line during amber time of 4 sec. If the reaction time of driver is assumed as 1 sec. then the average friction coefficient developed is [Take g = 9.81 m/s²]
