Two tugboats pull a disabled supertanker. each tug exerts a constant force of 1.60×106 n, one at an angle 13.0 west of north, and the other at an angle 13.0 east of north, as they pull the tanker a distance 0.700 km toward the north.

what is the total work done by the two tugboats on the supertanker?

express your answer in joules, to three significant figures.

You are your friend move a new refrigerator into his kitchen. you apply a horizontal force of 252 n in the negative x direction to try and move the 56 kg refrigerator. the coefficient of static friction is 0.61. (a) how much static frictional force does the floor exert on the refrigerator? give both magnitude (in n) and direction. magnitude n direction (b) what maximum force (in n) do you need to apply before the refrigerator starts to move?
