(a) Explanation Given info: The mass of satellite is 1940 kg , the radius of orbit is 12600 miles Write the expression to calculate the orbit velocity of Satellite. v = G m e r Here, v is the orbit velocity of satellite. G is gravitational constant. m e is the mass of Earth. r is the radius of orbit. The value of gravitational constant is 6.64 × 10 − 11 Nm 2 / kg 2 . The mass of Earth is 5.97 × 10 24 kg . Substitute 6.67 × 10 − 11 Nm 2 / kg 2 for G , 5.97 × 10 24 kg for m e and 12600 miles for r in above equation. v = 6.67 × 10 − 11 Nm 2 / kg 2 × 5 (b) To determine The energy required to move the satellite.

Central Force

Central force is the force that acts along the center of mass of one body to the center of mass of another body. Its direction from or away from a point on a body to another is called the center of the force. Such forces include gravitational force betwe…

The energy to place a satellite into orbit consists of the work against gravity and addition kinetic energy. In this problem, you get the chance to calculate both components (gravitational and kinetic). (There is also 'wasted' energy to lift and propel the fuel, but we are ignoring that in this problem and focusing only on the bare minimum.) What is the gravitational work required to launch a satellite of mass m from Earth's surface to a circular orbit at an altitude of 700 km? Express your answer in terms of m, g, and R. Please use at least 5 significant figures in your answers. Constants you may find useful: G = 6.67 x 10-11 N·m2/kg2; MEarth = 5.98 x 1024 kg; REarth = 6.38 x 106 m. _______ *mgR How much kinetic energy must be added, assuming the satellite is launched from the equator, where the initial velocity is 463 m/s? _______ *mgR What is the total energy per kg of payload? (Use g=9.80 m/s2.)_______ MJ/kg

Find the potential energy of a 50 kg mass that is 200 miles above the surface of the Earth. Youcan get the values of mass and radius of the earth from the book.(3,958.8 mi)

A space telescope of mass 696 kg is in Low-Earth Orbit, moving at a constant speed of 7200 m/s (approx. 26,000 km/h). Calculate the kinetic energy of the satellite in kilo-Joules (kJ).
