Question

The Work Done in Pulling a Supertanker Constants I Periodic Table Part A Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.90 106 N, one at an angle 17.0 west f north, and the other at an angle 17.0 east of north, as they pull the tanker a distance 0.780 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.

Explanation / Answer

Work done, W = F s cos theta

Total work done, W = Work done by both tug boats

= 1.9 x 10^6 * 0.78 x 1000 * cos 17° + 1.9 x 10^6 * 0.78 x 1000 * cos 17°

= 2.83 x 10^9 J
