Answer 2

Answer:

It's too simple dear,

Suppose you are tied behind a car,

Now the car is moving,

You are tied with the help of a rope

Now when car moves, it pulls rope and rope pulls you

So rope is applying force, it's itself moving due to the car pulling it

Now it don't matter whether you are running due to the rope pulling you or whether you are getting dragged,

rope is doing work because you are displaced!

Thanks
