 a. PE1 = 2PE2
  b. PE1 = 4PE2
  c. PE1 < 2PE2
  d. PE1 > 2PE2 but is not equal to 4PE2

Question 2

A careful photographic survey of Jupiter's moon Io by the spacecraft Voyager 1 showed active volcanoes spewing liquid sulfur to heights of 70 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. 260 m/s
  b. 530 m/s
  c. 790 m/s
