Homework Help: Grrr gravity

  1. Nov 22, 2006 #1
    grrr.... gravity

    A rocket is launched straight up from the earth's surface at a speed of 1.90×104 . What is its speed when it is very far away from the earth?
    plugging everything into the energy conservation theorem i came up with the exact same speed... i'm not sure what i'm doing wrong.
