Two cars collide at an icy intersection and stick togetherafterward. The first car has a mass of 1450 kg and is approachingat 8.5 m/s due south. The second car has a mass of 850 kg and isapproaching at 16.5 m/s due west.
(a) Calculate the magnitude of the final velocity, in meters persecond, of the cars.
(b) Calculate the direction of the final velocity, in degreessouth of west, of the cars.
(c) What is the change in kinetic energy, in joules, for thecollision? (This energy goes into deformation of the cars.)
