Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1050 kg and was approaching at 9.00 m/s due south. The second car has a mass of 800 kg and was approaching at 22.0 m/s due west. (a) Calculate the final velocity of the cars. Magnitude & Direction. (b) How much kinetic energy is lost in the collision? (This energy goes into deformation of the cars.)
