Problem

A toy car moves in a straight line under the following conditions: (i) First

3\,\text{m}

with a constant force of

4\,\text{N}

in the direction of motion, (ii) Next

2\,\text{m}

with a constant force of

6\,\text{N}

still in the direction of motion, (iii) Last

1\,\text{m}

with a constant force of

5\,\text{N}

opposite to the direction of motion. Determine the total work done on the car over the entire

6\,\text{m}

journey. a)
