If v represents the velocity or speed of the car when the brakes are first applied and d represents the distance it takes for the car to come to a complete stop then we can write a formula for the braking distance of a car with good tires on a level road d 0 0194v v is measured in ft s and d is measured in ft Note ft is a standard abbreviation for feet and s is a standard abbreviation for seconds Match each of the five quantities equations below with a reasonable interpretation from the list of choices below that You do not have to use all of the choices from the list d 40 d 50 d 50 d 40 d 60 d 50 d a 300 a A car traveling a ft s will come to a complete stop in 300 ft b The change in braking distance required if the speed increased from 40 ft s to 50 ft s c The distance it takes for a car traveling 40 ft s to come to a complete stop
