Problem

A box slides

3\,\text{m}

due east on a smooth horizontal surface while two constant forces act on it simultaneously:

\mathbf{P}=4\,\text{N}

due east and

\mathbf{Q}=5\,\text{N}

due north. What is the total work done on the box by these two forces? a)

27\,\text{J}

12\,\text{J}

19.2\,\text{J}

15\,\text{J}
