Question

Seems tried to push a heavy rock of 100 kg for 200s but could not move it find the work done by seem a at the end of 200s

Answer 1

Hey there !

Solution :

Work Done = Force * Displacement

Given :

Force = x

Displacement = 0

Work Done = Force * Displacement 

Work Done = x * 0 m 

We know that, anything multiplied by 0 is 0. Hence,

Work Done = 0 J

Even though there was energy loss in this activity ( work ), the net amount of work accounts to zero as there was no displacement of the rock from it's original position. Hence it is 0 J.

Hope my answer helped :-)
