show that the sum of kinetic energy and potential energy (i.e.,total mechanical energy) is always conserved in the case of a freely falling body under gravity (with air resistance neglected ) from a height h by finding it when (1) the body is at the top , (2) the body has fallen a distance x , (3) the body has reached the ground.
