Answer: stopping distance
Step-by-step explanation:
To drive safely at night, reduce your speed so your total __stopping distance________distance does not exceed the distance you can see ahead using your headlights.
stopping distance: This is defined as the distance the driver of a car can bring a car to complete stop safely in order to avoid hazards or accidents. This depends on factors such as reflex of the car and the surface of the road
mathematically stated as d = v^2/2ug
where d = stopping distance
v = velocity
u = coefficient of static friction
g = acceleration due to gravity
