Work done to lift the rock is 6174 Joule.
To find the answer, we need to know about the work done.
What's the work done?
Mathematically, work done = force × distance
What's the gravitational force acts on the stone here?
The gravitational force on the stone = mg
= 210× 9.8= 2058N
What's the work done to lift the stone?
Work done= 2058× 3
= 6174 Joule
Thus, we can conclude that the work done to lift the stone is 6174 Joule.
