Awhite car is traveling at the legal speed limit v0 along an interstate highway. a blue car traveling in the same direction at twice the legal limit draws alongside the white car and (mistakenly) thinks it is a police car. the blue car slows down with constant acceleration a = −ab and the white car continues at its previous constant speed. how far apart are the cars when the blue car’s speed is the legal speed limit?

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.
