Applied Mechanics and Graphic Statics
Newton’s Law of Motion is:

To every action, there is always an equal and opposite reaction
The rate of change of momentum is directly proportional to the impressed force, and takes place in the same direction, in which the force acts
Everybody continues in its state of rest or of uniform motion in a straight line, unless it is acted upon by some external force

Applied Mechanics and Graphic Statics
The masses of two balls are in the ratio of 2 : 1 and their respective velocities are in the ratio of 1 : 2 but in opposite direction before impact. If the coefficient of restitution is ½, the velocities of separation of the balls will be equal to

Original velocity in the opposite direction
Half the original velocity in the same direction
Original velocity in the same direction
Half the original velocity in the opposite direction
