  1. An imaginary planet has a mass twice as great as the Earth’s (5.97 x 10^24 kg), but the same radius (6.38 x 10^6 m).

    1. What is the acceleration due to gravity on the surface of the planet?

    1. What would be the weight of a 60 - kg robot on that planet?

    1. At what altitude (height from the surface of that planet) would a 60-kg person weigh 300 N?

    1. The period of rotation of this planet is 20 hours. At what altitude would you launch a satellite to be in geosynchronous with the planet rotation?

    2. What would be the orbital speed of that satellite?

The small spherical planet called "Glob" has a mass of 6.50×1018 kg and a radius of 5.60×104 m. An astronaut on the surface of Glob throws a rock straight up. The rock reaches a maximum height of 1.64×103 m, above the surface of the planet, before it falls back down. -What was the initial speed of the rock as it left the astronaut's hand? (Glob has no atmosphere, so no energy is lost to air friction. G = 6.67×10-11 Nm2/kg2.)...
