At time to a comet is observed at radius ro traveling with speed vo at an acute angle a to the line from the comet to the sun. put the sun at the origin 0, with the comet on the x axis (at to) and its orbit in the xy plane, and then show how you could calculate the parameters of the orbital equation in the form r = c/[1 + e cos(0 — 8)]. do so for the case that ro = 1.0 x 10 11 m, vo = 45 km/s, and a = 50 degrees. [the sun's mass is about 2.0 x 10 30 kg, and g = 6.7 x 10-11 n•m2/s2.]
