Physics 1 CHS Room 1101 Greg Hein Secure C CH Work The Work Done in Pulling a Supertanker Constans Part A Two tugboats pull a disabled supertanksr Each tug exerts a constant force ofl 1 30-1 N one at an angle 180" west of norh, and the other at an angle 180 east off noth, as they pull the tankera distance 0 760 km toward the north What is the total work done by tThe two tlugboats on the sopertanker?

Explanation / Answer

here,

constant force , F = 1.3 * 10^6 N

theta = 18 degree

force applied by tug 1 , F1 = 1.3 * 10^6 * ( - sin(18) i + cos(18) j)

force applied by tug 2 , F2 = 1.3 * 10^6 * ( sin(18) i + cos(18) j)

net force , F = F1 + F2

F = 2.6 * 10^6 * cos(18) j N

s = 0.76 km j = 760 m

the net work done , W = F.s

W = 2.6 * 10^6 * cos(18) * 760 J

W = 1.3 * 10^9 J

the net work done by the tugboats on supertanker is 1.3 * 10^9 J
