A ball of mass 2.00 kg is traveling east at 5.00 m/s. Another ball of mass 4.00kg is traveling west at 2.00 m/s. The two balls meet in a head-on-perfectly elastic collision. If the collision is perfectly (completely) elastic, what is the velocity (magnitude and direction) of each ball after the collision?
