Suppose you were hanging in empty space at rest, far from the Earth, but at the same distance from the Sun as the Earth. What minimum speed would you need to have in order to leave the solar system entirely and never fall back toward the Sun? The mass of the Sun is 2 × 1030 kg and the radius of the Earth’s orbit is 1.5 × 1011 m.

Respuesta :

Answer:

V = 42187 m/s = 42.18 km/s

Explanation:

given data:

mass of sun is  [tex]= 2\times 10^{30} kg [/tex]

radius of earth orbit is [tex]1.5\times 10^{11} m[/tex]

minimum speed can be determined by using following formula

[tex]V = (\frac{2gM}{r}))^{1/2[/tex]}

where G is [tex]\times 10^{-11}[/tex]

Plugging all value to get desired value

[tex]V  =(\frac{2\times 6.674 \times 10^{-11}2\times 10^{30}}{1.5\times 10^{11}})^{1/2}[/tex]

V = 42187 m/s = 42.18 km/s
