Two cars collide at an icy intersection and stick together afterward. the first car has a mass of 1200 kg and was approaching at 6.00 m/s due south. the second car has a mass of 900 kg and was approaching at 24.0 m/s due west.

a. calculate the final velocity 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
magnitude incorrect: your answer is incorrect. m/s direction â° (counterclockwise from west is positive)

b. how much kinetic energy is lost in the collision? (this energy goes into deformation of the cars.)
