Four identical particles A, B, C and D move with equal speed v, along the diagonal of a square towards the centroid O of the square, beginning at the vertices. After the collision at O, A and C retrace their path with speed 2v, and B retraces its path with speed \(v\sqrt{2}.\) Speed of the particle D after the collision is

Q. 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 centroid $G$ of the triangle. If after collision, $A$ comes at rest, $B$ retraces its path with speed $v$, then the speed of $C$ after collision is

Q. Three particles $A,B$ and $C$ of equal mass $m$, move with equal speed $v$ along the medians of an equilateral triangle as shown in the 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?

Q. Four particles A, B, C, and D of equal masses are placed at the corners of a square. They move with equal uniform speed $V$ towards the intersection of the diagonals. After collision, A comes to rest, B traces its path back with same speed and C and D move with equal velocities in same direction. What is the velocity of C after collision?

Q. Three particles $A,B$ and $C$ of equal mass move with equal speed $V$ along the medians of an equilateral triangles as shown in the figure. 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 velocity of $C$?

Q. Three particles A, B and C of equal mass move with equal speed $V=5m{s}^{-1}$ along the medians of an equilateral triangle as shown in the figure. They collide at the centroid G of the triangle. After the collision, A comes to rest, B retraces its path with the speed $V=5m{s}^{-1}$. What is the speed of C?
