Условие

A comet’s orbit has the following characteristics: eccentricity e = 0.995; aphelion distance $r_a = 5 \cdot 10^4 AU$. Assume we know the mass of the Sun $M_S = 1.98 \cdot 10^{30} kg$, and gravitational constant $G = 6.67 \cdot 10^{-11} Nm^2/kg^2$. Determine the velocity of the comet at its aphelion.

(a) 34.76 m/s

(b) 20.57 m/s

(c) 187.91 m/s

(d) 63.38 m/s

(e) 9.19 m/s
