1. The problem statement, all variables and given/known data(adsbygoogle = window.adsbygoogle || []).push({});

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 the orbital velocity to be 7788 m/s

2. Relevant equations

P = -GMm/r

K = .5*m*v^2

3. The attempt at a solution

I plugged the numbers into the kinetic energy equation

.5*200 kg*(7788 m/s)^2

and got 6.07 E 9
