Subject: How high would a bullet go if fired from Io directly at Jupiter?

Would it go all the way?  Assume 4100 ft./sec for the muzzle velocity of 
the bullet and Jupiter is directly "above" your location on Io.  You aim 
directly at the center of Jupiter.  Would the bullet spiral inward to the 
cloud tops or fall back to the Io surface?  How far above Io is the point 
of equal gravitational attraction between the two bodies?  What is the 
value of "G" in the equation S=1/2 G T(squared) for Io and Jupiter?
