Q3. An object orbits a planet of mass M in an elliptical orbit as shown. ................... Three points in the orbit marked A, B, and C are where the object VC has distances from the planet rA, I'B, Ic, respectively, and speeds VA, TA TC C AG VB, VC, respectively. The only . .... orbital data known about the object are summarized as: TA = 1 X 108 m, VA = 2700 VA . . . . . VB m/s B I'B = 5 x 108 m vc = 300 m/s (a) (2 points) Calculate the distance rc in meters. motive(b) (3 points) Calculate the mass of the planet, M in kg.
