A particle on earth's surface is given a velocity euqal to its escape velocity. Its total mechanical energy with zero potential energy reference at infinite separation will be:

A projectile is launched from the surface of earth with a velocity less than the escape velocity. Its total mechanical energy is

Assertion : If a particle is projected from the surface of earth with velocity equal to escape velocity, then total mechanical energy is zero Reason : Total mechanical energy of any closed system is always negative.

Assertion : If a particle is projected from the surface of earth with velocity equal to escape velocity, then total mechanical energy is zero Reason : Total mechanical energy of any closed system is always negative.
