Answer 2

Concept Introduction:

The definition of work done includes both the forces applied to the body and the overall displacement of the body. A constant force F is present before to this block. The goal of this force is to move the body d meters in a straight line in the force's direction.

Given: W = F S cos ϴ,  Ѳ =$180$°

To Find:

We have to find the value of, work done.

Solution:

According to the problem,

W = F S cos ϴ;cos$180$°=$-1$

W=FScos$180$°= FS($-1)$=-FS

Final Answer:

The value of W is -Fs.
