Problem

While towing a stalled car, a mechanic pulls it with a rope making an acute angle

\theta

with the horizontal. The magnitude of the pulling force is

30\,\text{N}

and the car moves

40\,\text{m}

horizontally. If the work done by the force is

720\,\text{J}

, determine the value of

\theta

. a)

37^{\circ}

53^{\circ}

45^{\circ}

31^{\circ}
