Question: 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 500km (or even higher) above the surface. Io has a mass of 8.94 x 1022 kg and a radius of 1815km. Ignore any variation in gravity over the 500km range of the debris.
Part A: How high would this material go on earth if it were ejected with the same speed as on Io?
I need help to find how high this material would go on earth.
