Two tugboats traction a disabled supertanker. Each tug exerts a consistent force of 1.50*10^6 N, one in ~ an edge 15.0 degrees west that north, and also the other at an angle 15.0 degrees east the north, as they traction the tanker a distance 0.720 kilometres toward the north.

2 tugboats pull a disabled supertanker. Every tugboat exerts a constant force the 1.50 X 10^6 N, one at an edge 15.0 levels west of north, and also the other at an angle 15.0 levels east the north, together they pull the tanker a street 0.720 km toward the north.

Two tugboats pull a disabled supertanker. Every tugboat exerts a constant force of 1.50 X 10^6 N, one at an angle 15.0 degrees west that north, and also the other at an angle 15.0 degrees east that north, together they pull the tanker a distance 0.720 km toward the north.

The force exerted by every tugboat deserve to be split into 2 components: among them in the direction of the north and also the various other towards the east and the west. The components towards the west of the tugboat pulling in the direction 15.0 degrees west of north is equal to the component in the direction of the east of the tugboat pulling in the direction 15.0 degrees east of north. This cancel out.

The various other components add up to give a full 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 that the force and the street it acts because that is 720*3*10^6*cos 15 = 2086.3*10^6 J

The full work excellent by the two tugboats is 559*10^6 J.
