Comet is in an elliptical orbit around the Sun. Its closest approach to the Sun is a distance of 4.5 × 1010 m (inside the orbit of Mercury), at which point its speed is 9.2 × 104 m/s. Its farthest distance from the Sun is far beyond the orbit of Pluto. What is its speed when it is 6 × 1012 m from the Sun? (This is the approximate distance of Pluto from the Sun.)
Answers: 2
= 9.2×10⁴ m/s.
