An 8.0 kg object moving to the right at 6.0 m/s suffers a head on collision with a 4 kg mass moving at 9.0 m/s to the left. After collision, the 8.0 kg object bounces back at 4.0 m/s. Draw or describe a diagram that explains the situation. Determine the final velocity of the 4.0 kg object after collision.
