(a) If the probe is launched with an initial kinetic energy of 5.0 107 J, what will be its kinetic energy when it is 4.0 106 m from the center of Zero?

(b) If the probe is to achieve a maximum distance of 8.0 106 m from the center of Zero, with what initial kinetic energy must it be launched from the surface of Zero?

>>>>>>>>>>>>>>>>>>>>>>>>>>>>

What equation do I start with?

I tried using:

E = KE - GMm/R and came up with the wrong answer. Am I doing something wrong? PLEASE HELP!
