Two identical billiard balls collide. The first one is initially traveling at (2.2 m/s)i ^ − (0.4 m/s)j ^ and the second one at −(1.4 m/s)i ^ + (2.4 m/s)j ^ . Suppose they collide when the center of ball 1 is at the origin and the center of ball 2 is at the point (2R, 0) where R is the radius of the balls. What is the final velocity of each ball?
