Three particles \( A, B \) and \( C \) of equal mass move with equal speed \( V \) along the medians of an equilateral triangle as shown in the figure-4.143. They collide at the centroid \( G \) of the triangle. After the collision., \( A \) comes to rest, \( B \) retraces its path with the speed \( V \). What is the speed of \( C \) ?
