Given :-
Distance the chair is pushed = 10 m
Force applied by the boy = 40 N
To Find :-
The work done by the body.
Analysis :-
Here we are given with the distance covered by the force applied by the boy.
In order to find the work done substitute the given values from the question such that work done is equal to force multiplied by the distance.
Solution :-
We know that,
- f = Force
- s = Displacement
- w = Work done
Using the formula,
Given that,
Force (f) = 40 N
Displacement (s) = 10 m
Substituting their values,
⇒ w = fs
⇒ w = 40 × 10
⇒ w = 400 J
Therefore, the work done by the boy is 400 J.
