    How Much Energy Is Required to Launch a Satellite into Orbit?

    final kinetic = 6.065 E 9 J final potential = 1.211 E 10 J final total energy = -6.049 E9 J initial kinetic = 2.153 E 7 J (using Earth's rotational period of 463.9 s to find Earth's v) now here's where I am not sure for initial potential energy do you use the total radius or just the...

    How Much Energy Is Required to Launch a Satellite into Orbit?

    1. Homework Statement A satellite of mass 200 kg is launched from a site on Earth's equator into an orbit at 205 km above the surface of Earth. What is the minimum energy necessary to place the satellite in orbit, assuming no air friction? I also figured the orbital period to be 5300 s and...
