Man on a Boat: Center of Mass

Physics Ninja looks at the center of mass of a man walking across a boat.
The position of the center of mass shouldn't change because there is no net force acting on the system.

    GREAT video. So many other sources on the web explained this in the most complicated and convoluted way EVER, but this was really clear. Many thanks from a struggling college physics student!

    Can he get to the other side of the boat with no boat movement if he turns and moon-walks? push forward slide backwards? Could not resist, sorry; great video and thanks!

    If use direct formula for displacemnt of the boat viz = ml/M+l it comes out to be 1.38 m but you are getting 3.08 m displacemnt how?

    Hey hi... I had a doubt.. If the man is walking on the boat (which I assume is on frictionless surface) Then to a observer (outside the boat) would see that the man is standing still while the boat moves back right? (I hope you can visualise what I am trying to say) Like The boat the move back.... but the man would stay there... But in many simulations online, that is not what they show... Why is this? Will the man move ahead as well? IF yes, then how?

    If there is no friction then there would not have been any movement. Friction is a must. If there were no friction then the man would not have been able to push the boat backwards as you visualise. Hope you get what I mean.
