  • Force=50N
  • Displacement=10m
  • Time=10s

We know

[tex]\boxed{\sf Power=\dfrac{Work\:done}{Time}}[/tex]

[tex]\\ \sf\longmapsto Power=\dfrac{Force\times displacement}{Time}[/tex]

[tex]\\ \sf\longmapsto Power=\dfrac{50\times 10}{10}[/tex]

[tex]\\ \sf\longmapsto Power=\dfrac{500}{10}[/tex]

[tex]\\ \sf\longmapsto Power=50W[/tex]
