A satellite orbits the earth at a height of 400 km above the surface. How much energy must be expended to rocket the satellite out of the earth’s gravitational influence? Mass of the satellite = 200 kg; mass of the earth = 6.0 ×1024 kg; radius of the earth = 6.4 ×106 m; G = 6.67 × 10–11 N m2 kg–2.​

Answer:

How much energy must be expended to the satellite to rocket out of the earth's gravitational influence? The total energy of the satellite is zero, if the satellite just escapes from the gravitational field. Therefore, 5.89 x 109J of energy has to supplied to the satellite to escape the gravitational pull.
