Given:-

  • Mass of body=m=15kg
  • Height=h=10m
  • Acceleration due to gravity=g=10m/s
  • Time=5min=300s

To find:-

Power

Solution:-

  • Find potential energy first

\boxed{\sf E_p=mgh}

\\ \sf\longmapsto E_P=15\times 10\times 10

\\ \sf\longmapsto E_P=15\times 100

\\ \sf\longmapsto E_P=1500J

Now

\boxed{\sf Power=\dfrac{Work\:done}{Time}}

\\ \sf\longmapsto Power=\dfrac{E_P}{Time}

\\ \sf\longmapsto Power=\dfrac{1500}{300}

\\ \sf\longmapsto Power=5J/s

\\ \sf\longmapsto Power=5Watts
