momentum
A person of mass mA is holding on to one end of a pole while another person of mass 2mA is holding onto the other end while standing on ice.
The pole has mass 3mA. They begin pulling towards each other such that they both have a velocity u with respect to the pole. They eventually pass each other and each reaches the other side of the pole--when they have switched places, how far has the pole's center of mass moved?
