A satellite is placed in orbit 2.75 x 105 m above the surface of Jupiter. Jupiter has a mass of 1.90 x 1027 kg and a radius of 7.14 x 107 m. Find the orbital speed of the satellite.

Jupiter's gravitational constant is
GM = 6.67259X10^(-11)(1.9X10^27)

The orbital radius R is 7.14x10^7 + 2.75x10^5

The velocity required for a satellite to remain in circular orbit derives from
V = sqrt[R/GM]
