Total work done is calculated as
[tex]\begin{gathered} \text{work}=\text{force}\times dis\tan ce \\ \text{ =20N}\times10m \\ \text{ =200 J} \end{gathered}[/tex]The power is calculated as ,
[tex]\begin{gathered} \text{Power}=\frac{work}{\text{time}} \\ \text{ =}\frac{\text{200 J}}{10\text{ sec}} \\ \text{ =20 W} \end{gathered}[/tex]
