You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 41.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 18.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . How fast (in miles per hour) was car A traveling just before the collision? (This problem uses English units because they would be used in a U.S. legal proceeding.)

You have been hired as an expert witness by an attorney for a
trial involving a traffic accident. The attorney's client, the
plaintiff in this case, was traveling eastbound toward an
intersection at 13.2 m/s as measured just before the accident by a
roadside speed meter, and as seen by a trustworthy witness. As the
plaintiff entered the intersection, his car was struck by a
northbound driver, the defendant in this case, driving a car with
identical mass to the...
