Concept

Problem: Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1200 kg and is approaching at 8.00 m/s due south. The second car has a mass of 850 kg and is approaching at 17.0 m/s due west. The final velocity is 8.46 m/s directed at 235°.How much kinetic energy is lost in the collision? (This energy goes into deformation of the cars.)
