Answer to Question #143685 in Physics for Sydney

Question

Sandy pulls a boat a distance of 15.8 meters along a dock using a rope that makes an angle of 20.0o with the horizontal. If she uses a force of 888 N, calculate work?

Answer 1

By the definition of the work done, we have:

$$W=Fscos\theta=888\ N\cdot 15.8\ m\cdot cos20.0^{\circ}=13184\ J.$$

Answer:

$W=13184\ J.$
