The net force in the system is initially balanced and the system is in equilibrium.
1) As John ducks, two things happens. First, there is a sudden impulse from his end which will change the momentum of the system from zero to an amount Mv proportional to the impulse Ft, which will be directed away from his direction because,
2) the process of ducking pushes his center of mass forward, which also moves the center of mass of the whole system away from him. This two effect will cause the skateboard to move forward.

When Galileo got ahold of a little telescope ... no more than
a kid's toy today ... he soon turned it towards the night sky.
The story says that he was the first one to do that. Apparently
everyone else who had these things used them to look at their
neighbors' windows. Anyway, When Galileo looked at Jupiter,
he saw four tiny dots. As he watched them night after night, he
saw that the four dots always stayed with Jupiter, but got nearer
and farther from it. He eventually realized that they were small
bodies in orbit around Jupiter. And then ... because he was Galileo ...
he made the big intellectual jump: He reasoned that if there were
smaller bodies in orbit around Jupiter, then Jupiter and the other
planets might also be in orbit around something, and not necessarily
around the Earth. He understood this as evidence that the sun is
the center of the solar system.
