Problem

A toy car on a smooth table is simultaneously acted upon by three horizontal forces:

10\,\text{N}

towards the east,

4\,\text{N}

towards the west, and

3\,\text{N}

towards the west (friction). What is the net horizontal force on the car, and what will be its resulting motion? (a)

17\,\text{N}

east; the car will start moving east. (b)

0\,\text{N}

; the car will remain at rest. (c)

3\,\text{N}

east; the car will start moving east. (d)

6\,\text{N}

east; the car will start moving east.
