2. Two tugboats attempt to pull a barge across the harbor. The barge exerts a force of 7500 N north, while the tugboats exert a combined force of 9500 N south. Are the tugboats able to move the barge?

your answer is, orbit around the nucleus

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

the components of a vector are the parts of the vectors that are to each other.
