I need help with this one, please. I think I may have part a but I'm pretty lost on part b

8. [-15 Points] OSCOLPHYSZO16 8.6.P.05IJ. ASK YOUR TEACHER PRACTiCE ANOTHER Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1800 kg and was approaching at 6.00 n'Ms due south. The second car has a mass of 800 kg and was approaching at 19.0 mr's due west. (3) Calculate the final velocity (magnitude in mg's 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 yaxis; instead, you must look for other simplifying aspects.) direction \\:I counterclockwise from west (l3) How much kinetic energy (in J) is lost in the collision? (This energy goes into deformation of the cars.) |:|J
