Two tugboats pull a disabled supertanker. Each tug exerts a construct force of 2.00 x 10^6 N, one at an angle 17 degrees west of north, and the other at an angle 17 degrees east of north, as they pull the tanker a distance 0.900 km toward the north.
(a) What is the total work done by the two tugboats on the supertanker?
