A satellite is placed in orbit 7.70 105 m above the surface of Jupiter. Jupiter has a mass of 1.90 1027 kg and a radius of 7.14 107 m. Find the orbital speed of the satellite.

I suggest you review Kepler's third law. You will find the equation you need there.
Another way to do it is to set
V^2/R = G M/R^2 where G is the universal constant of gravity, and M is the mass of Jupiter, and solve for V.
Make sure you use the distance of the satellite from the CENTER of Jupiter in the formula. It is
R = 7.217*10^7 m
