The work done in lifting a box on to a platform does not depend upon how fast it is lifted up. Explain your answer giving proper reasoning.

The work done in lifting a box on to a platform does not depend upon how fast it is lifted up, it depends upon the mass of the box and the height to be lifted.

as $W=mgh$

When $W\rightarrow$ Work done 

$m\rightarrow$ mass of the box

$g\rightarrow$ gravitational acceleration 

$h\rightarrow$ height to be lifted

Thus, it is clear from the formula that the work done to lift a box does not depend upon how fast it has been lifted.
