Question

A wooden chair is dragged on the level floor and brought to the same place . Let the distance covered be s and frictional force acted on the chair by the floor be f what is the work done by the frictional force by brainly

Answer 1

Answer:

hope this answer will help you

Answer 2

The work done is zero.

Explanation:

Given that,

Distance = s

Force = f

We need to calculate the  work done

Using formula of work done

$W=Fd\cos\theta$

Where, F = force

d = displacement

Put the value into the formula

$W=f\times0\times\cos\theta$

$W=0$

Here, displacement is zero because wooden chair is dragged on the level floor and brought to the same place .

Hence, The work done is zero.
