Kinetic energy would be obvious = 0.5mv^2
and the potential Energy would be= -Gm/r^2
Now total energy = 0.5mv^2 – Gm/r^2 hence would be negative as r approaches infinity.

Negative. For the velocity than escape velocity, the missle is bound due to the gravtitaion field of the earth. Hence its total energy is negative

Total energy is conserved, hence for the complete motion total energy is k.e+ P.e.
K.e = -p.e/2=-t.e( total energy).
T.e is negative.
