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 14.0 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 plaintiff's. The vehicles stuck together after the collision and left parallel skid marks at an angle of ? = 63.4° north of east, as measured by accident investigators. The defendant is claiming that he was traveling within the 35 mi/h speed limit. What speed was the defendant actually traveling at? 1. The defendant was traveling at 31.3 mi/h. 2. The defendant was traveling at 46.9 mi/h.     3. The defendant was traveling at 62.6 mi/h.
