Consider a Man having mass M and holding two balls each 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 . (state True or false statement) 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. 4) The man will do more work when he threw first ball than that of second ball
