P.028 Two automobiles of equal mass approach an intersection. One vehicle is traveling with velocity 12.0 m/s toward the east and the other is traveling north with speed v2 Neither driver sees the other. The vehicles collide in the intersection and stick together, leaving parallel skid marks at an angle of 60.5 north of east. Determine the initial speed v2i of the northward-moving vehicle m/s The speed limit for both roads is 35 mi/h and the driver of the northward-moving vehicle claims he was within the speed limit when the collision occurred.
