An object is pulled in different directions by four forces: 25 N, 40° south of east; 32 N, 30° north of east; 28 N, southwest, and 15 N, east. Find the resultant force.
East --> +25 cos 40 + 32 cos 30 - 28 cos 45 + 15
North--> -24 sin 40 + 32 sin 30 - 28 sin 45 + 0
Resultant = sqrt (East^2 + North^2)
tan angle clockwise from North = East/North
