a satellite with a mass of 1800 kg is placed at an altitude of 594 km above the surface of Europa. What is the strength of the gravitational force on the satellite?
The formula for gravitational potential energy is Ep= mgh. Lets convert 594 km into m: 594 x 1,000 = 594,000 m. So we do: Ep= (1,800kg)(9.8N/kg)(594,000m) = (17,640N)(594,000) = 10,478,160,000 J.
