Concept explainers
Stopping distance, The stopping distance of an automobile is the distance travelled during the driver’s reaction time plus the distance travelled after the driver applies the brakes. In an experiment, researchers measured these distances (in feet) when the automobile was traveling at a speed of
and the braking distance
(a) Determine the polynomial that represents the total stopping distance
(b) Use the result of part (a) to estimate the total stopping distance when
(c) Use the bar graph to make a statement about the total stopping distance required forincreasing speeds.
