Answer :-
Mass of man = 50 kg
_________________________
Explanation :-
Given:-
- Potential energy (P) = 2500 J
- Height of tree (h) = 5 m
- According due to gravity (g) = 10 m/s²
Find:-
- Weight of the man.
Solution:-
Energy possesed by an object due to change in it's shape or position is known as Potential energy.
- It is denoted by U.
- It's S.I. unit is joule (J).
And in above question, the man change his position to do the work. The energy possesed by him is knwon as Potential energy.
OR
Substitute the known values in above formula
•°• Mass of the man is 50 kg

Find:-
The weight of the man.
Hence:-
Note That :-
• Let U be the Denoted and Joule be the SI unit.
• Let (J) be the joule.
[Formula]
Potential energy = mass × acceleration of gravity × height.
Adding values
Therefore, 50kg is the weight of the man.
