John is in a  lab performing an experiment on collision. John takes a 3.0 kg car and sets it moving right with a speed of 1.0 m/s. This car collides with a second car of mass 6.0 kg that John has given a speed of 3.0 m/s left. After the collision, John notes the 3.0 kg car is moving 1.0 m/s left. From this, what would John observe as the velocity of the 6.0 kg car?     A. 2.0 m/s to the right   B. 0.80 m/s to the left   C. 0.80 m/s to the right   D. zero m/s   E. 2.0 m/s to the left
