A weight lifter lifts a mass m at contant speed to a height h in time t how much work w is done by weight lifter?

The weight of the mass 'm' is (m g) .

That's the minimum force he has to exert in order to balance the force of gravity and

lift the weight vertically. If he exerts more force than (mg), the weight will accelerate

up, and he'll just wind up either coasting in the middle, or else retarding it at the top.

So the eventual outcome is just applying the force (mg) through the distance 'h'.

The time taken for the maneuver has no effect on the work done. It's just the amount of

potential energy gained by the bar-bell due to its increased elevation.

Work = [ (force) times (distance) ] or [ (weight) times (height) ].

W = m g h
