Question
Three forces act on a moving object. One force has a magnitude of 82.0 N and is directed due north. Another has a magnitude of 64.0 N and is directed due west. What must be the magnitude and direction of the third force, such that the object continues to move with a constant velocity?
° south of east
I can't get the correct direction for this. I have tried arc tan of 82.0/64.0, but it doesn't seem to make much sense.
magnitude 104 N direction° south of east

Explanation / Answer
F3 should be = east is +i
64 i - 82j
F = sqrt(64^2 + 82^2)
F = 104 N
direction = tan^-1(82/64)
theta = 52.03 south of east
