Problem

0.35\,\text{m}

long wrench is pulled with a constant

50\,\text{N}

force. The force is always applied at

90^{\circ}

to the wrench as it turns from

\theta = 0

\theta = \dfrac{\pi}{2}\,\text{rad}

. Approximately how much work is done on the wrench during this rotation? a)

55\,\text{J}

27\,\text{J}

17.5\,\text{J}

14\,\text{J}
