A particle of mass , initially moving with a velocity of
collides elastically with a particle of mass
, initially moving with a velocity of
. What are the velocities of the two particles before and after the collision in the centre of mass frame of reference? What are the velocities of the two particles after the collision in the laboratory frame?
In the center of mass (CM) frame of reference, the velocities of the two particles before and after the collision can be determined by first calculating the velocity of the center of mass (V_cm). For two particles of masses ( m_1 ) and ( m_2 ), with initial velocities ( v_1 ) and ( v_2 ) in the laboratory ____ ______ _____ ___ _____ _________ ____ ____ _________ ______ ___ _________.
