Question: Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.90Ã-106 N , one at an angle 15.0 ∘ west of north, and the other at an angle 15.0 ∘ east of north, as they pull the tanker a distance 0.640 km toward the north.
What is the total work done by the two tugboats on the supertanker? Express your answer in joules, to three significant figures.
