This weightlifter did work on the barbell to lift it over her head.
Calculate the work done in lifting a 500-N barbell 2.2m above the floor what is the potential energy of the barbell when it is lifted to this height?
Work = Force x distance So since the barbell is 500N and the barbell travels 2.2 meters it becomes 500N x 2.2m = 1100 joules (N x m)
The weight lifter used a force of 980N to raise the barbell over her head in 521 seconds approximately how much work did she do in raising the barbell?
5105.8 J
If a weight lifter lifts a barbell and then sets it down is any work done?
Answer: It depends upon your definition of "work". Assuming the lifter put the barbell back exactly where and how it was at first, then there was no work done in the physics context. If you mean manual labor, then yes, some work was done.

What forms of energy are used when someone lifts a barbell to momentary muscular failure?
I don't know what you mean by momentary muscular failure. Surely if this happens he won't succeed in lifting the barbell? Lifting a barbell or indeed any muscular work done involves chemical changes in the muscles which provide the energy required, in this case raising the weight against the force of gravity. The energy used to lift a weight m kg a height of h meters is 9.81 x m x h joules.
