Two cam collide at an icy intersection and stick together afterward The first car has a mass of 1290 kg and was approaching at 800 mfs due south. The second car has a mass of 850 kg and was approaching at 21.0 mfs due west. (a) Calculate the final velocity (magnitude in mls and direction in degrees counterclockwise from the west] of the cars. (Note that since both cars have an initial velocity, you cannot use the equations for conservation of momentum along the X-axis and y-axis; instead, you must look for other simplifying aspectsi] direction \\:I counterclockwise from west (b) How much kinetic energy (in J) is lost in the collision? (This energy goes into deformation of the cars) :J
