You are watching: What is the total work they do on the supertanker?
two tugboats traction a disabled supertanker. Each tugboat exerts a consistent force the 1.50 X 10^6 N, one at an edge 15.0 degrees west the north, and the other at an angle 15.0 levels east the north, as they pull the tanker a street 0.720 kilometres toward the north.

Two tugboats traction a disabled supertanker. Every tugboat exerts a continuous force the 1.50 X 10^6 N, one at an angle 15.0 levels west that north, and the other at an angle 15.0 degrees east the north, together they pull the tanker a distance 0.720 km toward the north.
The pressure exerted by every tugboat have the right to be divided into 2 components: one of them in the direction of the north and also the other towards the east and the west. The materials towards the west the the tugboat pulling in the direction 15.0 degrees west of phibìc is equal to the component in the direction of the eastern of the tugboat pulling in the direction 15.0 degrees east that north. This cancel out.
The various other components add up to provide a complete of 2*1.5*10^6*cos 15 = 3*10^6*cos 15.
As the tanker is pulled because that a distance 0.720 kilometres towards the north, the product the the force and the street it acts because that is 720*3*10^6*cos 15 = 2086.3*10^6 J
The full work done by the 2 tugboats is 559*10^6 J.
