1. Energy conservation can also be applied to planets orbiting the Sun in an elliptical orbit. The figure shows the orbit of Mars around the Sun. Point A is the maximum distance from the Sun and is called aphelion. Point D is the minimum distance from the Sun and is called perihelion. B uns E (a) At aphelion, Mars is 2.49x10" m from the Sun and it has a speed of 22.0 km/s. What is the kinetic energy of Mars at aphelion? What is its potential energy? What is its mechanical energy? Mars has a mass of 6.42x10 kg and the Sun has a mass of 1.99x100 kg
