What is the Gravitational Potential Energy of a 2 000 kg satellite on the surface of the Earth? O-6.25 x x 10^7 J O -4.32 x x 10^9 J O-1.25 x 10^11 J O - 2.80 x 10^11 J What is the TOTAL energy of the same satellite when it is in ORBIT at an altitude (or height) of 550 km above the Earth? O-5.76 x 10^10 J O -1.25 x 10^10 J O -6.25 x 10^10 J -2.16 x 10^10 J How much Work must be done to put the satellite into this orbit? Another way of saying this: How much MORE energy does it need to get from the Earth to this orbit? O6.74 x 10^10 J 1.09 x 10^10 J 3.37 x 10^10 J 4.98 x 10^10 J 3.38 km/s O 5.92 km/s 6.64 km/s O No What speed would the object need to have, at the surface of the Earth, to end 1 point up in orbit 550 km above the Earth? That is, how fast would the satellite need to be 'thrown' from Earth's surface to end up in the orbit we've described? O 8.21 km/s O 11.1 km/s 1 point Yes 1 point 1 point Try it in one step! Et1 = Eto - in order for the satellite to get into orbit it needs 1 point to have the same total energy at the surface of the earth, Et1, as it does in orbit, Eto. Plug in the correct values and solve for v1, the speed at the surface of the Earth. Do you get about 8 200 m/s?
