Question : 4

Total: 40

Solution:

Work done

(W)=

Force

(F) \times

Distance

(D), W = F \times D

Since the distance is what is being calculated for, make the distance the subject

Dividing both sides of the equation by force,

Work done

/

Force

=

Distance

\Rightarrow

Distance

=

Work done

/

Force

Work done

=60

and Force

=20

\Rightarrow

Distance

= \frac{60}{20} = 3.0 \, \text{m}
