Problem

3\,\text{kg}

parcel on a loading dock experiences three horizontal forces:

12\,\text{N}

due east,

16\,\text{N}

due south, and

9\,\text{N}

due west. Which of the following gives both the magnitude of the parcel’s acceleration and its direction measured south of east? a)

5.4\,\text{m/s}^2

11^{\circ}

south of east b)

8.8\,\text{m/s}^2

37^{\circ}

south of east c)

5.4\,\text{m/s}^2

79^{\circ}

south of east d)

1.8\,\text{m/s}^2

79^{\circ}

south of east
