A comet orbits the sun (mass m_S) in an elliptical orbit of semi-major axis a and eccentricity e What is the kinetic energy of the comet at perihelion and aphelion in terms of its speeds at these points and its mass mm? (Express your answers in terms of the variables v_a, v_p, and m) What is the potential energy of the comet at perihelion and aphelion in terms of the sun–comet distances at these points, its mass m, and the mass of the sun m_S? (Express your answers in terms of the variables r_a, r_p, m, m_S and gravitational constant G) Derive expressions for the magnitudes of angular momenta with respect to the sun at perihelion and aphelion in terms of comets speeds and the sun–comet distances at these points. (Express your answers in terms of the variables v_a, v_p, r_a, r_p, and m separated by a comma)
