On a frictionless table, two stationary balls are placed along the y-axis with their contact being centered on the origin of the XY-plane. A third ball moves along the x-axis toward the pair with an initial velocity V. What will be the velocity (magnitude and angle) of all three balls after the collision? Assume that the three balls are physically identical and that the collisions are perfectly elastic. Show all work and explain the results.
