Problem

A particle experiences a piecewise constant force along the

x

-axis while moving from

x = 0

x = 6\,\text{m}

: •

F = +4\,\text{N}

for

0 \le x < 2\,\text{m}

•

F = -2\,\text{N}

for

2\,\text{m} \le x < 5\,\text{m}

•

F = +3\,\text{N}

for

5\,\text{m} \le x \le 6\,\text{m}

(a) Calculate the work done in each interval. (b) Determine the net work done over the entire

6\,\text{m}

displacement.
