Consider a person having mass M and holding two balls every of mass m is at rest over a frictionless surface. Now the person throws one ball towards right direction with velocity " v " w.r.t himself . After 1 second he throws another ball towards left direction with velocity " v " w.r.t himself .
1) The final velocity of Man = 0
2) Center of mass would not change.
3) The momentum of each ball after thrown will be equal.
