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...

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.

During calculation of acceleration due to gravity above the surface of earth if we assume that there is an external force opposite to that of Earth's gravity then the cos angle will be 180 between the two forces which is negative(-1), if we put the value in the equation of dw = F.dx then the final value of potential energy is positive which is not possible.how and why??
