Given:-
- Mass of each bricks , m = 2.5 Kg
- No. of bricks ,n = 10 bricks
- Displacement ,s = 20 m
To Find:-
- Work Done ,W
Solution:-
When a force acting on a body and the body cover/displace for some distance . Then we said the Work is Done.
Total mass of bricks = 10×2.5 = 25 kg
• W = Fs
where,
- W denote Work Done
- F denote force of
- s denote displacement
Substitute the value we get
→ W = 25 × 20
→ W = 500 J
- Therefore,the work done by the body is 500 Joule.

Note : W = Fs Cos(theta) where , F = Force , s = displacement , theta = Angle b/w F and s

Answer:
Given :-
- A person carrying 10 bricks each of mass is 2.5 kg on his head moves to a distance of 20 m.
To Find :-
- What is the work done.
Formula Used :-
★ Work Done = Force × Displacement ★
Solution :-
Given :
- Force = 2.5 kg = 2.5 × 10 = 25 kg
- Displacement = 20 m
According to the question by using the formula we get,
⇒ Work Done = 25 × 20
➠ Work Done = 500 J
∴ The work done by a body is 500 J .
