https ://session mastenngphysics.com/myt itemiew?assignmentproblemiD-889ST745 Weekly 08: Work, Kinetic Energy, and Potential Energy Item 12 Two tugboats pull a disabled supertanker. Each tug exerts a constant force of 1.90 10 N.one at an angle 10.0 west of north, and the other at an angle 10.0 east of north, as they pull the tanker a distance 0.770 km toward the north Part A What is the total work done by the two tugboats on the supertanker? Express your answer in joules, to three significant figures > View Available Hint(s) Submit X Incorrect: Try Again; 24 attempts remaining Provide Feedback

Explanation / Answer

Total Force is

Ftotal=FCos10+FCos10=2FCos10

Ftotal=2*(1.9*106)*Cos10=3,74*106 N

Total Work done is

W=Fd= (3.74*106)(0.77*103)

W=2.88*109J
