# Calculate the work done

## Homework Statement

Two tugs pull a tanker. Each at a force 1400000N with one at an angle 14degrees west of north, the other 14degrees east of north. They pull the tanker 0.66km north.

W=Fs

## The Attempt at a Solution

I simply took the vector force of 1 tanker

1400000Cos(14) = 1358414N multiplied it by two for both tugs = 2716828

Therefore W (asked in 3 sig figs) = 2716828*0.66 = 1.79*10^6Nm

Unfortunately I'm told this is wrong

Appreciate any help!

You forgot the distance!

OK... you put in the distance (good!), but the distance is measured in km, not meters.
