As depicted below an asteroid is situated half way between two dwarf planets.  a) calculate the net force on asteroid  b) find acceleration of astroid

Satellite in Orbit 12 3? 5 6 Scientists want to place a 4100 kg satellite in orbit around Mars. They plan to have the satellite orbit a distance equal to 1.5 times the radius of Mars above the surface of the planet. Here is some information that will help solve this problem: mmars = 6.4191 x 1023 kg "mars = 3.397 x 106 m G = 6.67428 x 10-11 N-m?/kg? 1) What is the force of attraction between Mars and the satellite? Submit + 2) What speed should the satellite have to be in a perfectly circular orbit? m/s Submit 3) How much time does it take the satellite to complete one revolution? hrs Submit 4) Which of the following quantities would change the speed the satellite needs to orbit at? O the mass of the satellite O the mass of the planet O the radius of the orbit Submit 5) What should the radius of the orbit be (measured from the center of Mars), if we want the satellite to take 8 times longer to complete one full revolution of its orbit? m Submit

The escape velocity on the surface of the Moon is 2.4 Km/sec, and the radius of the Moon is 0.27 Earth's radius. Find the mass of the Moon from this. Screenshot

I Review The Attraction of Ceres Ceres, the largest asteroid known, has a mass of roughly 8.7 x 1020kg. Part A If Ceres passes within 1.2x104 km of the spaceship in which a 66 kg astronaut is traveling, what force does it exert on she? (Treat the astronaut and the asteroid as point objects.)
