A cart of mass M is tied to one end of a massless rope of length 10m. The other end of the rope is in the hands of a man of mass M. The entire system is on a smooth horizontal surface. The man is at x=0 and the cart at x=10m. If the man pulls the cart by the rope, the man and the cart will meet at the point
