A planet is in an elliptical orbit around a distant star. At its closest approach, the planet is 0.710 AU from the star and has a speed of 54.0 km/s. When the planet is at its farthest distance from the star of 41.0 AU, what is its speed (in km/s)? (1 AU is the average distance from the Earth to the Sun and is equal to 1.496 ✕ 1011 m. You may assume that other planets and smaller objects in the star system exert negligible forces on the planet.)
