A crew member is walking on a tugboat that is pulling a barge. The tugboat is moving at a constant speed upstream in a river that has a constant downstream current. 2. In the situation above, a dockhand measures the magnitude and direction of the velocity of the tugboat’s crew member as +vc relative to the dockhand. In terms of vc, what is the magnitude and direction of the velocity of the dockhand relative to the crew member?
