Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1050kg and is approaching at 9.5 m/s due south. The second car has a mass of 650kg and is approaching 18m/s due west. Calculate the direction of the final velocity in degrees south of west of the cars. What is the change in kinetic energy, in joules for the collision? (This energy goes into deformation of the cars
