$-$ Part $($a$)$

Calculate the magnitude of the final velocity, in meters per second, of the cars.

$-$ Part $($b$)$

Calculate the direction of the final velocity, in degrees south of west, of the cars.

$$ Part $($c$)$

What is the change in kinetic energy, in joules, for the collision? $($This energy goes into deformation of the cars.$)$
