\mathrm{r}_{1}

and

\mathrm{r}_{2}

being its closest and farthest distances, respectively, from the center of the planet. If the satellite has a speed

\mathrm{v}_{1}

at its closest distance, what is its speed at its farthest distance? (A)

\frac{r_{1}}{r_{2}} v_{1}

(B)

\frac{r_{2}}{r_{1}} v_{1}

(C)

\frac{r_{1}+r_{2}}{2} v_{1}

(D)

\frac{r_{2}-r_{1}}{r_{1}+r_{2}} v_{1}
