Centre of mass



  • Five identical pigeons are flying together northward with speed v0. One of
    the pigeons is shot dead by a hunter and the other four continue to fly with
    the same speed. Find the centre of mass speed of the rest of the pigeons
    which continue to fly with the same speed after the dead pigeon has hit the
    ground.



  • @mrjain-jain as there is no ext force in horizontal direction so com will continue to move with the same horizontal velocity with which it was moving before
