Answer:-

Try this formula:

W= Fd

F = W by d

Explanation:-

(Note: A newton-meter is the same thing as a joule, so the units for work are the same as those for energy – joules).

The force required to lift a rock at a vertical distance of 8 m if 80 j of work were done is 10 N.

What is force?

A force is an effect that can alter an object's motion. Due to force, an object with mass can change its velocity, or accelerate.

Given,

Distance is 8 m

work done is 80 j

Now by the formula of work

[tex]\bold{Work = force \times distance}[/tex]

[tex]80= F\times 8\\\\F= \dfrac{80}{8} = 10 N[/tex]

Thus, the force required is 10 N.
