Two cars collide at an icy intersection and stick together afterward. The first car has a mass of1350kg and was approaching at6.00m/sdue south. The second car has a mass of900kgand was approaching at25.0m/sdue west.

(a)Calculate the final velocity (magnitude in m/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 thex-axisandy-axis;instead, you must look for other simplifying aspects.)magnitude m/sdirection counterclockwise from west

(b)How much kinetic energy (in J) is lost in the collision? (This energy goes into deformation of the cars.)
