For each of the following systems of forces as a result of considering the components of each force, determine the resultant force (a) 2 N in an easterly direction, 3 N at 60° west of north and 2 N due south, (b) 4 N in a north-easterly direction, 3 N due west and 5 N at 30° south of east, (c) 2.8 N in a north-easterly direction, 4 N at 60° south of west and 6 N at 30° south of east.
