Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1450 kg and is approaching at 9.5 m/s due south. The second car has a mass of 650 kg and is approaching at 17.5 m/s due west. Part (a) Calculate the magnitude of the final velocity, in meters per second, of the cars. Part (b) Calculate the direction of the final velocity, in degrees south of west, of the cars. Part (c) What is the change in kinetic energy, in joules, for the collision? (This energy goes into deformation of the cars.) Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1450 kg and is approaching at 9.5 m/s due south.
