An exoplanet is in an elliptical orbit around a distant star. at its closest approach, the exoplanet is 0.540 au from the star and has a speed of 54.0 km/s. when the exoplanet 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 exoplanet.)

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
