Jupiter's moon Io has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject material as high as 500 km (or even higher) above the surface. Io has a mass of 8.93×1022kg and a radius of 1821 km.

How high would this material go on earth if it were ejected with the same speed as on Io? ( RE =6370km , mE=5.96×1024kg )
Include variations in gravitational acceleration

The material will go as high as 91.54 km would this material go on earth if it were ejected with the same speed as on Io.

What is will be the height of the material on earth?

The height of the material on earth will be derived from the given values as follows:

  • Gravitational constant, G = 6.67 × 10⁻¹¹ m³/kgs²
  • radius of Io, r = 1821000 m
  • mass of Io, m =  8.93 × 10²² kg
  • Height of materials, H = 500000 m
  • acceleration due to gravity on Earth, g = 9.81 m/s²

Tue acceleration due to gravity on Io, go is given as:

[tex]g_o = \frac{GM}{r^{2}}[/tex]

Substituting the values:

[tex]g_o= \frac{6.67×10^{-11}×8.93×10^{22}}{1821000^{2}}[/tex]

[tex]g_o = 1.796 m/s^{2}[/tex]

Height on earth, He and Height on Jupiter H is given as follows:

[tex]H_e = \frac{v^{2}}{2g}[/tex]

[tex]H = \frac{v^{2}}{2g_o}[/tex]

Taking ratio of the two heights and solving for height on earth, He:

[tex]H_e = H × \frac{g_o}{g}[/tex]

Substituting the values:

[tex]H_e = 500000 × \frac{1.796}{9.81} = 91539.245 m[/tex]

Therefore, the material will go as high as 91.54 km would this material go on earth if it were ejected with the same speed as on Io.
