Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 2.10×106 N, one at an angle 16.0° west of north, and the other at an angle 16.0° east of north, as they pull the tanker a distance 0.680 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.
