Question

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

Answer 1

Three particles A, B and C of equal mass move with equal speed V along the medians of an equilateral triangle as shown in figure. They collide at the centroid G of the triangle. After the collision, A comes to test, B retraces its path with the speed V. COLM : implies that →vC & →vB are opposite to each other.
