A cart of mass \( M \) is tied by one end of a massless rope of length \( 10 \mathrm{~m} \). 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 \( x=10 \mathrm{~m} \). If the man pulls the cart by the rope, the man and the cart will meet at the point
