The driver of a vehicle sees an object on a level road 150m in front of them and takes evasive action to stop. The vehicle is traveling at 110 kph. The reaction time for the driver is two seconds and the coefficient of longitudinal deceleration is 0.41. Calculate the speed the vehicle be travelling at when they strike the object. Your answer should be rounded up to the nearest km/hr and gravity should be taken as 9.81m/s2.
