Three men are trying to move a wardrobe. One pushes northward with a force of 100N; the second pushes eastward with a force of 173N; the third pushes in a direction 60 degrees west of south with a force of 200N. What is the resultant force on the wardrobe and it's direction?

Answer 1

north at 100N = (0,100)
east at 173N = (173,0)
S60°W at 200N = (-173,-100)

add them up to get (0,0)
