Hey. Heres the question:(adsbygoogle = window.adsbygoogle || []).push({});

"A weightlifter lifts a 100kg mass 2.4m from the floor. He then holds the mass steady for 3 seconds before dropping it. What is the work done by the weightlifer in raising the mass?"

Well. I know mass is applying a force downward of 980N because of gravity, so for this question, since an acceleration of the mass is not stipulated, do i just calculate the work as the MINIMUM amount of work he would do? Which would be around 2352J, so for the answer, would i just say that he must do MORE THAN 2352J of work to lift the weight?
