Three particles each of mass m are located at the vertices of an equilateral triangle ABC. They start moving with equal speeds v each along the medians of the triangle and collide at its centroid G. If after collision, A comes to rest and B retraces its path along GB, then C...

Expert Answer:

According to conservation of momentum,
 
Initial momentum Pi = final momentam Pf
 
Initially all the particles were at rest.
Therefore Initial momentum Pi = 0
 
 
Hence, in order to conserve momentum, the velosity of particle C will be same as velosity of particle B but in opposite direction.
 
C will go in opposite direction of B.
