A car of mass 1.20 kg travels due east at a speed of 37.0 m/s before colliding with a parked car of mass 1.80 kg. After the collision, the first car moves in the direction of 55.0° north of east while the second car moves in the direction of 27.0° south of east. How fast are (a) the first car and (b) the second car going after the collision?

1st car = 20.4 m/s 2nd car = 17.0 m/s

Since this is an elastic collision, using M1V1+M2V2=M1v1+M2v2, the first car would end up having a speed of 17.0 m/s and the second car would have 20.4 m/s.
