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. In the situation above, what is at rest relative to the tugboat?
what is the barge?
the barge is like a carrier that is used on rivers to ship things.
To determine what is at rest relative to the tugboat, we need to consider the motion of different objects involved.
In this scenario, the crew member is walking on the tugboat, which is moving upstream in a river with a constant downstream current. The speed of the tugboat is constant. To determine what is at rest relative to the tugboat, we need to identify an object or point that is not moving relative to the tugboat.
In this case, the only object that is at rest relative to the tugboat is the crew member themselves. When the crew member walks on the deck of the moving tugboat, they are moving at the same speed and in the same direction as the tugboat. Since their motion matches that of the tugboat, they appear to be at rest relative to the tugboat.
So, in this scenario, the crew member is at rest relative to the tugboat.
