Two cars collide at an icy intersection and stick together afterward. the first car has a mass of 1100 kg and is approaching at 8.5 m/s due south. the second car has a mass of 750 kg and is approaching at 16 m/s due west. part (a) calculate the magnitude of the final velocity, in meters per second, of the cars. a numeric value is expected and not an expression. part (b) calculate the direction of the final velocity, in degrees south of west, of the cars. a numeric value is expected and not an expression. part (c) what is the change in kinetic energy, in joules, for the collision? (this energy goes into deformation of the a numeric value is expected and not an expression
