V FarlA lo' a satellite of Jupiter. is the most volcanically active moon or planet in the solar system It has volcanoes that send plumes of matter over 500 In]: high. Due to the satellite's small mass' the acceleration due to gravityr on In is only'l Bl mfg? and lo has no appreciable atmosphere Express your answef in meters per second Assume that there is no variation in gravity over the distance traveled. *5 a o ? What must be the speed of material just as it leaves the volcano to reach an altitude of 390 km? muest Answer V FarlB lithe gravitational potential energy is Zero at the surface, what is the potential energy for a 18 kg fragment at its maximum height [500 km) on Io?
