Physics Question?

The police are investigating an accident. They have determined that the m of car A is 2275kg and the m of car B is 1525kg. From the skid marks and date for the friction btw tires and concerte, the police determined that the cars, when they were locked together, had a velocity of 31km/h at angle of 43 degrees north of the eastbound street. If the speed limit was 35km/h on both streets, should one or both cars be ticketed for speeding?
