A tugboat is pulling a barge into a harbor. The barge is exerting a force of 3000 N against the tugboat.Which force would most likely allow the tugboat to move the barge into the harbor?

The barge pushes back against the tugboat with 3000 N, so the tugboat must pull in the opposite direction with a force greater than 3000 N to overcome that resistance. A 4500 N pull in the opposite direction would allow the tugboat to move the barge into the harbor. A 3000 N pull would only balance the opposing force.
