Need help on this page A comet has a mass of 20000 kg semi major axis a= 1.5 e11 m with an eccentricity e=0.6.The mass of the sun is 2.0 e30 kg.8.It turns out that that you can find the period of the comet by assuming the orbit is circular and thenusing the semi major axis as the radius. Find the period of this comet.9. Find the total mechanical energy of the comet10. Using conservation of energy find the velocity of the comet at Aphelion.11. Using conservation of momentum find the velocity of the comet at perihelion.

8. A comet has a mass of 20000 kg semi major axis a= 1.5 e11 m with an eccentricity e=0.6. The mass of the sun is 2.0 e30 kg. turns out that that you can find the period of the comet by assuming the orbit is circular and then sing the semi major axis as the radius. Find the period of this comet. 9. Find the total mechanical energy of the comet
