A careful photographic survey of Jupiter's moon Io by the spacecraft Voyager 1 showed active volcanoes spewing liquid sulfur to heights of 60 km above the surface of this moon. If the value of g on Io is 2.0 m/s2, estimate the speed with which the liquid sulfur left the volcano.
 a. 120 m/s
  c. 490 m/s
  b. 240 m/s
  d. 970 m/s

 a. 2800 m/s
  c. 5600 m/s
