Each tug exerts a constant force of 1.5*10 north, as they pull the tanker a distance 0.61 km toward the north. N, one an angle 19° west of north and the other an angle 19° east of Part A What is the total work they do on the supertanker? Express your answer using two significant figures W 1.8.10 Submit My Answers Give Up Incorrect; Try Again; 3 attempts remaining Continue

Explanation / Answer

Find the force that one of the tugboats exerts;
1.5 x 10^6cos19
=1418277.86N
This number is the same for both of them.

W=Fs
1418277.86x (0.61x1000)
= 8.65x10^8 J each.

Therefore total work = 2 x (8.65x10^8)
= 1.73 x 10^9 J
