Acar traveling at 30 miles per hour requires 90 feet to come to a cineplete stop d=distance s=speed and m is the constant

use d=ms^2 and solve for m

just plug in the information:

d=90

s=30

so 90=m*30^2

90=m*900

 now divide both sides by 900 to get m

 m=0.1

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
