Two automobiles of equal mass approach an intersection.One vehicle is traveling with velocity 13.0 m/s toward theeast, and the other is traveling north with velocity v 2i. Neitherdriver sees the other. The vehicles collide in the intersectionand stick together, leaving parallel skid marks at an angle of55.0° north of east. The speed limit for both roads is 35 mi/h,and the driver of the northward-moving vehicle claims he waswithin the limit when the collision occurred. Is he telling thetruth?
