(7%) Problem 13: Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1400 kg and is approaching at 5.5 m/s due south. The second car has a mass of 750 kg and is approaching at 17 m/s due west. 33% Part (a) Calculate the magnitude of the final velocity, in meters per second, of the cars. v=6.93 Correct! A33% Part (b) Calculate the direction of the final velocity, in degrees south of west, of the cars. 33% Part (c) What is the change in kinetic energy, in joules, for the collision? (This energy goes into deformation of the cars.) AKE= Gr De Por
