Two cars collide at an icy intersection and stick together afterward. The first car has a mass of 1500 kq and was approaching at 4.00 m/s due south. The second car has a mass of 750 kg and was approaching at 23.0 m/s due west. (3) Calculate the final velocity (magnitude in mys 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 aspects.) magnitude my's direction Enter a number, x . counterclockwise from west (b) How much kinetic energy (In ]) is lust in the collision? (This energy goes into deformation of the cars.)
