Center of MassHard
Question
Two particles approach each other with different velocities. After collision, one of the particles has a momentum 
in their center of mass frame. In the same frame, the momentum of the other particle is
in their center of mass frame. In the same frame, the momentum of the other particle is Options
A.0
B.−
C.− /2
/2D.− 2
Solution
In centre of mass frame total momentum of the system is always zero.
Hence momentum of other particle is −.
Hence momentum of other particle is −
