PLZ HELP! What would happen to work and power if the mass of the person walking was increased or decreased? EXPLAIN.

The work done on the mass is then W = Fd = mgh. We define this to be the gravitational potential energy (PE g) put into (or gained by) the object-Earth system. This energy is associated with the state of separation between two objects that attract each other by the gravitational force.

hopefully im right that came from the top of my head so tell me if im wrong!! :)

the answer is 75.0%.
