Hola User_______________________
Here is Your Answer....!!!!!_____

〽⤵⤵Actually welcome to the concept of the Work - Power And Energy ....
〽⤵⤵Basically we can see here ...there is no velocity for the body ...while climbing the the height thus ...the Maximum Potential Energy gained by it is given as
〽⤵⤵P.E. = Mgh. ...
〽⤵P.E. = (50) (9.8) (100)
========》 49000 JOULES ....
〽⤵⤵Thus the Potential Energy gained is 4.9 × 10^4 j.....
〽⤵⤵In this case the Work done = Potential Energy gained ...
〽⤵⤵thus Work done = 4.9 × 10^4 ...j

Hope it helps u......☺
Answer:
Potential Energy = mgh.
Given, m=40kg ; g =9.8 m/s² ; h = 200m
• 40×9.8×200
• 78400 J
is the answer.
