A crane lifts a 487 kg beam vertically at a constant velocity. If the crane does 5.20 x 10^4 of work on the beam find the vertical distance that it lifted the beam?
I understand the equation that needs to be used to solve the problem. What don't I understand is how does the coefficient of gravity(g) which is 9.8m/s plays a role in this question. Can someone kindly explain this part for me?

Vertical distance
Explanation:
The only force involve in the crane is the weight
The force of the weight
Force of the crane is equal to weight directed upward (positive)
The work
God bless....I hope the explanation is useful.
