Tugboats are used to pull large loads through shallow water canals. NASA used tugboats to deliver large barges carrying fuel to launch sites. The barges weighed significantly more than each tugboat. Each barge carrying fuel weighed about 64,000 kg each and was pulled by 20-m-long steel cables. Type &

B. The tension on the barge is greater than the tension on the tugboat.

C. The net force on the tugboat is equal to the net force on the barge.
