**FredR**, Thursday, March 11, 2010 at 1:37amNewton's law of gravitation:

F = G m1 m2 /r^2

let m2 = mass of ice cube and

s = G m1/r^2

so,

F = s m2

rearranging,

s = m2/F

let V = orbital speed

centripetal acceleration = V^2/r

For an object to remain in orbit s must equal the centripetal acceleration so,

s = V^2/r

**drwls**, Thursday, March 11, 2010 at 3:07amTaking up where FredR left off,

V^2/r = G m/r^2

V^2 = G m/r

where m is the mass of Saturn.

G = 6.674*10^-11 N*m^2/kg^2

Solve for V
