(choose chapter or problem)

A zip line is installed 50 meters above ground level. It runs to a point on the ground 50 meters away from the base of the installation. Show that the work done by the gravitational force field for a 175-pound person moving the length of the zip line is the same for each path.

(a) \(\mathbf{r}(t)=t \mathbf{i}+(50-t) \mathbf{j}\)

(b) \(\mathbf{r}(t)=t \mathbf{i}+\frac{1}{50}(50-t)^{2} \mathbf{j}\)

Text Transcription:

r(t) = ti + (50 - t)j

r(t) = ti + 1 / 50 (50 - t)^{2}j
