The four balls each have the same mass m. a and b are rolling forward with velocity v and strike c. assume that the distance between the balls a and b is the same as the distance between the balls c and d. consider only two-body collisions. from the possible collisions between the neighboring balls the collision with the largest relative speed of one of the colliding balls relative to the other one will occur faster. take e = 0.5 between each ball.
