The driver of a car is initially moving at a constant speed

Reference no: EM13672105

The driver of a car is initially moving at a constant speed of 69.7 km/h when a traffic light turns red. If a 0.490 s reaction time is needed before the brakes can be applied, what is the distance in meters travelled by the car before it begins to slow down?
