Asunbather is lying on a floating raft that is stationary. she then gets up and walks to one end of the raft. consider the sunbather and raft as an isolated system.
(a) what is the velocity of the center of mass of this system while she is walking?
(b) does the raft itself move while she is walking? if so, what is the direction of the raft's velocity relative to that of the sunbather?
