1. The problem statement, all variables and given/known data 2 automobiles of equal mass approach an intersection. One vehicle is traveling with a velocity of 13.0m/s toward east and other is traveling north with a speed of [tex] v_2i [/tex]. The vehicles collide at the intersection become stuck together and leave parallel skid lines at an angle of 55.0 deg north of east. Speed limit for both cars is 35mi/h and the driver of th northward moving vehicle claims he was within speed limit when it occured. Is he telling truth? 2. Relevant equations 3. The attempt at a solution I don't have the masses so how do I do this problem?? I don't have the v2 so I assume I could work with 35mph speed as the initial speed of the other vehicle but other than that I'm not sure what to do... and I don't have final vf after collison 35mph=> 15.646m/s Help!
