(1s equal to pt) A s spacecraft of mass m is in a circular orbit around the Sun with the radius R average Earth-Sun distance. At point A, the spacecraft is firing its thrusters Sun, to point E the tangentially to the closer to the s e trajectory such that it will fall on an elliptical orbit, which will bring it un, to point B. At point B, it once again fires its thrusters tangentially to its ry to go...
A 16 kg satellite has a circular orbit with a period of 2.6 h and a radius of 9.4 × 106 m around a planet of unknown mass. If the magnitude of the gravitational acceleration on the surface of the planet is 7.7 m/s2, what is the radius of the planet?
The spaceship Asimov is in circular orbit (radius 6.02x107 m) about the planet Terminus. If it takes 5,004 seconds to orbit the planet, find the mass of the planet, in kg. Express your answer inscientific notation (using E for exponent).

10-3. A 639-kg satellite is in a circular orbit about Earth at a height h = 1.16 x 10^7 m above the Earth’s surface. Find (a) the gravitational force (N) acting on the satellite, (b) the satellite’s speed (m/s) (magnitude of its velocity, not its angular velocity), and (c) the period (h) of its revolution. Caution: The radius of the satellite’s orbit is not just its height above the Earth’s surface. It also includes the radius of the Earth. The...
