You are a member of a group of scientists who travel to planet Bubba, a planet that orbits a bright star in our southern sky. The radius of the planet is Rb = 5.0 x 106 m. You land on the planet. While you are standing on the surface of the planet you throw a small rock straight up with an initial speed of 6.0 m/s. The rock reaches a maximum height of 12.0 m above the point from which it was thrown. What is the mass of planet Bubba?
