2\,\text{kg}

block is pulled

4\,\text m

along the positive

x

-axis by three constant forces whose magnitudes and directions relative to the

x

-axis are: 1.

10\,\text N

0^{\circ}

, 2.

6\,\text N

60^{\circ}

, 3.

5\,\text N

120^{\circ}

. Calculate the net work done on the block during the displacement.
