Answer:

Yes

Step-by-step explanation:

Work done in this situation is equal to the directional potential energy. That is to say the body has been displaced from one position to another ( in this case it has to do with height )

And so

Force × displacement= mass(gravity) × height

However,no further work is done if the person remains at that position.
