When a car skids to a stop, the length L, in feet, of the skid marks is related to the speed S, in miles per hour, of the car by the equation
.
As speed increases, so does the length of the skid marks. What can you say about the rate of increase? A graph of L versus S can help you answer this question.
?
A. Skid mark length increases more rapidly as speed increases.
B. Skid mark length increases rapidly at first but slows as speed increases.
C. Skid mark length increases at a decreasing rate.
